President Donald Trump’s campaign filed a lawsuit in Michigan yesterday as part of its long-shot legal strategy to upend Joe Biden’s Nov. 3 election win, even as the former vice president focused on laying the foundation of his incoming administration.

The Republican president’s team went to federal court to try to block Michigan, a Midwestern battleground state that he won in 2016 but lost to the Democrat in media projections, from certifying the results.

Trump trailed by roughly 148,000 votes, or 2.6 percentage points, in unofficial Michigan vote totals.

Trump has declined to concede the election to Biden, instead lodging a flurry of lawsuits in pivotal states to try to back up his unsupported claims of widespread voting fraud. The Michigan lawsuit also made allegations of misconduct in the voting, with the focus on the Democratic stronghold of Wayne County, which includes Detroit.

Jake Rollow, a spokesman for the Michigan Department of State, said the Trump campaign was promoting false claims to erode public confidence in Michigan’s elections.

“It does not change the truth: Michigan’s elections were conducted fairly, securely, transparently, and the results are an accurate reflection of the will of the people,” Rollow said in a statement.

Prominent Republican lawmakers and other Trump allies have backed the president’s strategy, saying he has the right to contest the election results. The suit was filed one day after Biden called Trump’s failure to concede an “embarrassment.”

Judges have tossed out several of the Trump lawsuits, and legal experts say the litigation has scant chance of changing the election outcome.

Biden last Saturday clinched victory in the election as he won a series of battleground states to exceed the 270 electoral votes needed in the state-by-state Electoral College. Biden was winning the national popular vote by at least five million votes, with some states still counting ballots.

Biden and his wife Jill visited a war memorial in Philadelphia to mark Veterans Day yesterday before returning home to Delaware.

Trump placed a memorial wreath at the Tomb of the Unknown Soldier in Arlington National Cemetery in Virginia, outside of Washington. It was his first public appearance, other than two golf outings, since a White House news conference last Thursday in which he made unsubstantiated election fraud claims.

While Trump made no remarks at the cemetery, in Twitter posts yesterday he kept up his narrative of voter fraud, referring to “a mountain of corruption & dishonesty” while also assailing pollsters.

However, Georgia’s top election official said yesterday that the state will conduct a recount of all paper ballots cast in the presidential election.

“Mathematically, you actually have to do a full hand-by-hand recount of all because the margin is so close,” Georgia’s Secretary of State Brad Raffensperger said at a news conference. “We want to start this before the week is up.”
