California Gov. Gavin Newsom said he has all the evidence needed to believe "completely corrupt" President Donald Trump should be removed from office by Congress, but with Republicans in control of the U.S. Senate the best way to boot Trump from office is at the ballot box."I wouldn't support impeachment unless I supported removal," he said Tuesday, marking the first time he's explicitly stated senators should remove Trump from office. He's long backed impeachment, calling for hearings as early as 2017 when he was running for governor and the Russia investigation was consuming Washington.Still, he doesn't think it's likely to happen. The Republican controlled chamber "will simply do nothing but abdicate any traditional oversight of bad behavior of this administration," he said. He thinks voters, though, will choose a Democrat over Trump next fall.Newsom's comments came during an interview with The Associated Press, where he discussed California's ongoing feud with the Trump administration and the faltering presidential campaign of U.S. Sen. Kamala Harris of California, whom Newsom has endorsed.The first-term governor has made no secret of his disdain for Trump and his policies. California has filed roughly 60 lawsuits against administration policies on environment, immigration and more. Newsom has accused Trump of threatening aid to California as a form of political retribution and has not been shy in his criticism.Newsom did not specify whether Trump's request for Ukraine to investigate Joe Biden is what sparked his belief that Trump should be removed from office or whether he thought there was enough evidence to remove him prior. His office did not offer clarification.On the 2020 campaign, Newsom downplayed Harris's standing in a seeming effort to boost her candidacy, saying former Vice President Joe Biden, Vermont Sen. Bernie Sanders and Massachusetts Sen. Elizabeth Warren already had national brands when they launched their candidacies compared to Harris, who just won election to the Senate in 2016.Harris launched her campaign with an impressive crowd and much anticipation in January, but has seen her standing in national and California polls fall. She now ranks behind Biden, Warren and Sanders, hovering in a second-tier pack with South Bend, Indiana, Mayor Pete Buttigieg.Newsom added that he doesn't think the Trump campaign knows how to beat Harris, making her a particularly formidable candidate. Newsom is headlining a fundraiser for Harris later this month in Los Angeles with Hollywood power brokers such as Donna Langely, chairman of Universal, and producer J.J. Abrams.
