Kevin Kiley has garnered his most well-known  Democratic challenger yet in Dr. Richard Pan, the former state senator who once made national headlines for going toe-to-toe with Robert F. Kennedy Jr. as California pushed to enforce school vaccine mandates.  <\/p>\n\t\t\t\t\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\n\t\t\n<p>Republican Rep. Kevin Kiley\u2019s newest Democratic challenger might be even more well known to Sacramento-area voters than the two-term congressman who has represented the area since 2023.&nbsp;<\/p>\n\n\n\n<p>Dr. Richard Pan, a Harvard-trained pediatrician and former state senator who made national headlines for <a href=\"https:\/\/calmatters.org\/education\/2022\/01\/california-child-vaccine-mandates\/\">leading California\u2019s effort to eliminate<\/a> religious and \u201cpersonal belief\u201d exemptions to school vaccine mandates, announced his candidacy for California\u2019s 3rd Congressional District on Tuesday.&nbsp;<\/p>\n\n\n\n<p>Pan and Democrats nationwide hope to hold Republicans like Kiley accountable for supporting President Donald Trump\u2019s megabill, which over the next 10 years will cause an estimated 10 million Americans to lose health coverage under Medicaid and the Affordable Care Act, according to the <a href=\"https:\/\/www.cbo.gov\/publication\/61570\">nonpartisan Congressional Budget Office<\/a>.<\/p>\n\n\n\n<p>\u201cWe see a federal government that seems to be intentionally attacking health care, whether it&#8217;s taking away people&#8217;s health insurance, undermining public health to allow disease to spread, cutting research for things like cancer treatments,\u201d Pan told CalMatters in an interview.&nbsp;<\/p>\n\n\n\n<p>\u201cAs a pediatrician, I&#8217;ve spent my life really trying to keep kids and their families healthy,\u201d he added. \u201cI\u2019m running for Congress to be sure that we can protect people\u2019s health care.\u201d<\/p>\n\n\n\n<p>Pan joins Democrats <a href=\"https:\/\/www.tv4ca.com\/\">Tyler Vandenberg<\/a>, a Marine Corps veteran and <a href=\"https:\/\/www.stripes.com\/branches\/marine_corps\/2023-12-14\/marine-jeopardy-winner-tyler-vandenberg-12358502.html\">former \u201cJeopardy!\u201d winner<\/a>, y <a href=\"https:\/\/www.heidihall.com\/\">Heidi Hall<\/a>, an environmental advocate and Nevada County supervisor, who launched campaigns against Kiley earlier this year.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-proposition-50-would-remake-the-district\">Proposition 50 would remake the district<\/h2>\n\n\n\n<p>Kiley\u2019s district is one of five that would shift to favor Democrats if California voters next month approve a plan to gerrymander the state&#8217;s congressional districts \u2013 <a href=\"https:\/\/calmatters.org\/california-voter-guide-2025\/\">known as Proposition 50<\/a>.<\/p>\n\n\n\n<p>While the district he represents currently spans much of the California-Nevada border and is in largely rural, forested areas, the new seat would encompass many of Sacramento\u2019s eastern neighborhoods and suburbs, including Auburn, Rancho Cordova and Folsom. The new district would also include Grass Valley, Truckee and the California portion of Lake Tahoe, as well as the Eldorado National Forest.<\/p>\n\n\n\n<p>Kiley, who has branded himself as a Republican foil to Gov. Gavin Newsom, has been a vocal opponent of Prop. 50 and accused the governor of targeting his seat because of his attempts to \u201cNewsom-proof California\u201d in Congress by eliminating the state\u2019s ban on gas-powered cars and halting federal funding for high-speed rail.<\/p>\n\n\n\n<p>\u201cThere&#8217;s a reason Newsom sent his own staffer to run against me last year,\u201d Kiley <a href=\"https:\/\/x.com\/KevinKileyCA\/status\/1972013682046468216\">wrote on social media last month<\/a>, referring to Democrat Jessica Morse, \u201cand has now made me the number one target of his redistricting sham.\u201d<\/p>\n\n\n\n<p>Pan, a Sacramento resident who supports Prop. 50, has previously represented about 70% of voters who live in what would become the new district, according to his campaign.<\/p>\n\n\n\n<p>By challenging Kiley, whom Pan has characterized as a \u201crubber stamp\u201d for House Republicans and Trump\u2019s agenda, Pan hopes to also serve as a check on the Trump White House and a former nemesis of his own, Health and Human Services Secretary Robert F. Kennedy Jr.&nbsp;<\/p>\n\n\n\n<p>Pan started pushing to eliminate religious and personal belief exemptions to school vaccine requirements after public health experts traced the origin of a 2014 measles outbreak to an unvaccinated Disneyland traveler. His 2015 bill, and a subsequent measure in 2019 to strengthen that original law, ignited Kennedy\u2019s anti-vaccine activist allies and prompted harassment from opponents, death threats and <a href=\"https:\/\/www.capradio.org\/articles\/2019\/08\/21\/california-state-sen-richard-pan-shoved-near-capitol-by-opponent-of-vaccine-exemption-bill\/\">physical violence<\/a> against the then-state senator.&nbsp;<\/p>\n\n\n\n<p>\u201cI even had blood thrown at me and got assaulted on the street, but I didn\u2019t back down,\u201d Pan said of the bills he led that ended religious and personal belief exemptions for school vaccination requirements. He said Americans \u201cshould be very disturbed and concerned and worried\u201d about Kennedy\u2019s leadership.&nbsp;<\/p>\n\n\n\n<p>The son of Taiwanese immigrants, Pan said he first ran for the state Assembly in 2010 to address the gridlock he saw in California\u2019s government. He said he watched as <a href=\"https:\/\/www.kqed.org\/news\/9747\/20\">local hospitals struggled to make payroll<\/a> because state lawmakers couldn\u2019t agree on a budget. Now, seeing the same thing in Washington, D.C., he said he wants to make the government \u201cwork for people\u201d again \u2013 which he says Kiley failed to accomplish despite at times paying lip service to bipartisanship and pushing to outlaw mid-decade redistricting nationwide.&nbsp;<\/p>\n\n\n\n<p>\u201cTalk is easy,\u201d Pan said. \u201cWhen push comes to shove and you get to that bill where you basically get to choose between, \u2018Do I support the president&#8217;s agenda, or do I defend the people in my district?\u2019 he chose to support the president&#8217;s agenda.\u201d<\/p>\n\n\n\t<div\n\t\tclass=\"wp-block-newspack-blocks-homepage-articles cm-manual-eoa-recirc wpnbha show-image image-alignleft ts-3 is-1 is-landscape cm-manual-eoa-recirc\"\n\t\tstyle=\"\"\n\t\t>\n\t\t<div data-posts data-current-post-id=\"478045\">\n\t\t\t\t\t\t\t<h2 class=\"article-section-title\">\n\t\t\t\t\t<span>READ NEXT<\/span>\n\t\t\t\t<\/h2>\n\t\t\t\t\t\t\n\t<article data-post-id=\"492460\"\n\t\tclass=\"tag-environment tag-gavin-newsom tag-riverside-county tag-water tag-water-pollution category-environment legislator-steve-padilla-165435 type-post post-has-image\"\n\t\t\t\t>\n\t\t\t\t\t\t\t<figure class=\"post-thumbnail\">\n\t\t\t\t\t\t\t\t<a href=\"https:\/\/calmatters.org\/_es\/environment\/2026\/04\/salton-sea-conservancy\/\" rel=\"bookmark\" tabindex=\"-1\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"900\" src=\"https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=1200%2C900&amp;ssl=1\" class=\"attachment-newspack-article-block-landscape-large size-newspack-article-block-landscape-large wp-post-image\" alt=\"California\u2019s largest and most polluted lake gets a new conservancy\" data-hero-candidate=\"1\" srcset=\"https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=1200%2C900&amp;ssl=1 1200w, https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=800%2C600&amp;ssl=1 800w, https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=600%2C450&amp;ssl=1 600w, https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=400%2C300&amp;ssl=1 400w, https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=200%2C150&amp;ssl=1 200w, https:\/\/i0.wp.com\/calmatters.org\/wp-content\/uploads\/2026\/04\/020423-Geothermal-Lithium-AD-CM-07.jpg?resize=1200%2C900&amp;ssl=1&amp;w=370 370w\" sizes=\"auto, (max-width: 34.9rem) calc(100vw -

Miller covers politics and government accountability for CalMatters, with one eye on the state Legislature and the other on California's congressional delegation in Washington, D.C. She will help lead CalMatters' coverage of campaigns, voters and elections in the run-up to the 2026 midterms. Maya came to CalMatters in June 2025 by way of the New York Times, where she covered Congress as the David E. Rosenbaum fellow in Washington, D.C. She hit the 2024 campaign trail and delivered deeply reported stories from five different states across the country. From Nebraska, a deep red state, Maya introduced readers to an independent candidate \u2013\u2013 a mechanic with no political experience \u2013\u2013 who nearly unseated Republican Senator Deb Fischer after riding a populist wave. And in Maine, she showed readers how Representative Jared Golden, a three-term Democrat, persuaded Trump voters in his in his conservative-leaning district to split their tickets. From the halls of the Capitol, Maya reported on how constituents overwhelmed the Congressional phone system shortly after President Donald J. Trump's inauguration as outraged Democrats and energized Republicans tried to get the ear of their elected officials. She covered House Republicans' herculean effort to pass Trump's ambitious domestic policy agenda and also explained how the G.O.P. 's unprecedented repeal of California's Clean Air Act waivers threatened to blow another hole in the filibuster. Prior to the New York Times, Maya reported for The Sacramento Bee, where she resurrected the dormant state worker beat, reported closely on contract negotiations and pioneered a newsletter that informed more than 250,000 civil servants in California. She has also reported for The Seattle Times, the Minnesota Star Tribune and the Des Moines Register. Maya graduated from Duke University with a degree in public policy. She grew up in Des Moines and credits the Iowa caucuses with sparking her love for journalism and current events.
