Members of the Michigan state Legislature’s Republican leadership who met with President Donald Trump at the White House Friday afternoon said they haven’t seen any evidence that would change the fact that President-elect Joe Biden won their state. “We have not yet been made aware of any information that would change the outcome of the election in Michigan and as legislative leaders, we will follow the law and follow the normal process regarding Michigan’s electors, just as we have said throughout this election,” Senate Majority Leader Mike Shirkey and Michigan House Speaker Lee Chatfield said in a joint statement after their meeting with the President. It was a blow to Trump, who had invited the lawmakers to the White House this week, as he seeks to subvert the will of voters in a long-shot effort to overturn the results of an election he lost. The President’s efforts to pressure local leaders, which earned sharp criticism even from some Republicans, come as his legal team’s options to challenge election results in states he lost are rapidly evaporating and as states move to certify their election results. MAP: See 2020 election results Michigan is scheduled to certify its election results Monday afternoon, and the GOP lawmakers who met with Trump on Friday committed to letting that certification process play out and undercut the false claims of nationwide voter fraud that Trump and his allies have continued to peddle. “Michigan’s certification process should be a deliberate process free from threats and intimidation,” the lawmakers said in their statement. “Allegations of fraudulent behavior should be taken seriously, thoroughly investigated, and if proven, prosecuted to the full extent of the law. And the candidates who win the most votes win elections and Michigan’s electoral votes. These are simple truths that should provide confidence in our elections.” A person familiar with Friday’s meeting said the session was cordial as the group explained to the President the process for certifying the election and assigning electors in their state. Trump did not apply any overt pressure on the lawmakers to try and shift electors from Biden to himself, or to prevent the vote from being certified, the person familiar with the meeting said, but the President did appear interested in the explanation the lawmakers offered. The leaders said they also talked about Covid-19 relief with the President, and delivered a letter requesting more federal funds to fight the pandemic. They had accepted Trump’s invitation to the White House meeting, they said, “as we would accept an invitation from any sitting President if asked to meet at the White House.” Shirkey and Chatfield stayed overnight at the Trump hotel and left Washington Saturday morning, a source familiar told CNN. On Saturday, Trump responded to the two Michigan lawmakers’ statement about their meeting, saying in a tweet that it was “true” but vowing, without providing any evidence, that fraud would be shown. “This is true, but much different than reported by the media. We will show massive and unprecedented fraud!” the President wrote on Twitter. White House insists it’s ‘not an advocacy meeting’ Trump had extended the invitation on Wednesday evening to the Michigan lawmakers by calling Shirkey. Shirkey did not responded to emails from CNN, and his phone mailbox was also full. Michigan state House Speaker-elect Jason Wentworth was also scheduled to attend the meeting with the President, a source familiar said ahead of the meeting. White House press secretary Kayleigh McEnany earlier on Friday would not say what Trump was planning to discuss with the Michigan lawmakers. “This is not an advocacy meeting. There will be no one from the campaign there. He routinely meets with lawmakers from all across the country,” McEnany said. Despite McEnany’s claim that campaign officials would not attend, Giuliani, who has been leading the campaign’s legal effort, had told Fox 5 New York he would be at Friday’s meeting. But ahead of the meeting, an official familiar with the situation told CNN that Giuliani would no longer attend because he was in contact with someone with Covid-19. Giuliani is self-isolating in Washington, DC, after his son, Andrew – a special assistant to the President – tested positive for coronavirus Friday morning. Trump campaign lawyer Jenna Ellis tweeted Friday that both she and Giuliani tested negative for the coronavirus, adding, “The entire legal team will continue to follow the advice and protocols of our doctors.” Trump inserts himself into the certification process Certification is usually a formality, but Trump is trying to block or delay the process in key states as part of a long-shot effort to overturn his election defeat through the Electoral College. Giuliani and other allies have suggested that GOP state legislatures in battleground states Biden won should try to use a delay in certification to appoint their own slate of electors and ignore the states’ popular votes for Biden.

It’s not clear if those invitations have been extended yet, but Trump has expressed interest in doing so as he tries to insert himself into the vote certification process. The deadline for counties in Pennsylvania to certify their totals is Monday. Earlier this week, Trump called two Michigan Republican canvass board members from Wayne County to offer his support, after they went back and forth on voting to certify the county’s election results. The board members filed affidavits Wednesday seeking to “rescind” their votes to certify the election result, though Michigan Secretary of State spokeswoman Tracy Wimmer told CNN no legal mechanism exists from them to do so. Despite the efforts from Trump and Republicans, states have gone ahead with certifying their results, including Georgia, which on Friday officially granted the state’s 16 electoral votes to Biden. RNC and Michigan GOP ask for delay in certification The Michigan State Board of Canvassers is currently slated to meet virtually at 1 p.m. on Monday and certify the state’s election results, and Wimmer told CNN that they expect the board to do so. “We have no reason to doubt the canvassers will carry out their duty to certify. Every one of Michigan’s 83 counties have done so, Republican and Democrat clerks have confirmed there is no evidence of widespread irregularities, and the board has previously certified elections with more clerical mistakes and much narrower margins of victory,” Wimmer said in a statement to CNN. On Saturday, the Michigan Republican Party and Republican National Committee sent a letter to the board asking them to delay certification for 14 days and wait for an audit of Wayne County’s election results – even though state law doesn’t allow that. An audit cannot be conducted until certification is complete and Wayne County, which is the state’s largest county and includes Detroit, certified its results this week. Asking for an audit is also outside the purview of the board, whose only role is to canvass and certify election results. Both Shirkey and Chatfield have said that they will honor their state’s popular vote and not stray from the process of how electors in Michigan are selected. Biden currently has a 154,187 vote lead over Trump in the Great Lakes State. On September 24, Shirkey led the Senate to pass a resolution assuring that electors will vote for the candidate with the most votes as certified by election officials. “The Michigan Senate commits to the selection of electors to the Electoral College that will be faithful to voting for the candidate with the most votes for President in Michigan as certified by Michigan election officials,” the resolution read. Meanwhile, Black voters in Michigan are now suing the President and his campaign, claiming his bid to pressure state and local officials to block popular votes for Biden violates the Voting Rights Act. They say the pressure campaign to give electoral votes to Trump, despite Biden’s statewide wins, specifically seeks to disenfranchise Black voters. And a growing number of veteran GOP lawmakers are objecting to Trump’s tactics. Rep. Fred Upton, a senior Michigan Republican who was targeted by Democrats but won his reelection bid by 16 points, said, “Yeah. I think it’s all said and done.” “No one has seen any real identification of any real fraud,” Upton said. This story has been updated with additional developments.
