Despite pressure from US President Donald Trump to help overturn his election loss, Vice President Mike Pence will stick to his ceremonial duties and not block Wednesday’s certification by Congress of President-elect Joe Biden’s victory, advisers said. Trump ramped up pressure on Pence on Tuesday to block congressional certification of the November election results in an ongoing attempt to stay in power, after dozens of lawsuits by his campaign challenging the outcome failed in US courts. The vice president, a loyal lieutenant during the four years of Trump’s often chaotic presidency, has no plans to intervene and has told Trump he does not have the power to do so, even as he seeks to show support for the Republican president’s quest. Pence is set to preside over a joint session of Congress on Wednesday as it receives the results of the state-by-state Electoral College that determines the winner of presidential elections. Biden, a Democrat, beat Trump 306-232 in the Electoral College and in the popular vote by more than 7 million ballots. Trump has declined to concede the election. US states have already certified the results, and Pence’s role on Wednesday as president of the Senate is to “open all the certificates,” in the presence of the House of Representatives and the Senate, the US Constitution says. Trump suggested Pence could do more than that. “The Vice President has the power to reject fraudulently chosen electors,” Trump wrote in a tweet, his latest unfounded suggestion that the election was marred by widespread fraud. Pence told Trump on Tuesday he did not believe he had the power to block the certification, according to a source familiar with the subject. The New York Times first reported the contents of the conversation. In a statement released late on Tuesday, Trump denied the report. “The Vice President and I are in total agreement that the Vice President has the power to act,” Trump said. “Our Vice President has several options under the US Constitution. He can decertify the results or send them back to the states for change and certification.” Trump’s statement and tweet put more pressure on Pence, whose future political prospects are tied largely to his ability to please the president’s base of supporters. But advisers said on Tuesday night that the vice president’s thinking about his role had not changed. Trump’s pressure campaign against his vice president took off at a campaign rally for Republican US Senate incumbents in Georgia on Monday night when he expressed hope that Pence would take action. “If he doesn’t come through, I won’t like him quite as much,” Trump said. About a dozen Republican senators, as well as dozens of Republicans in the House, plan to object to the certification of the Electoral College results in Congress on Wednesday. The move has virtually no chance of overturning Biden’s victory.
