In a letter to House Speaker Mike Johnson, White House counsel Edward Siskel outlined testimony from the president's family members, their associates, and other witnesses that showed the "opposite of what House Republicans have claimed" regarding Biden improperly profiting from family members' business activities.
He also noted reporting that showed Republican lawmakers themselves saying the inquiry was falling apart and had not found impeachable offences or particular crimes.
The House in December to formally authorize the inquiry even in the absence of evidence of wrongdoing by the president. Republicans allege Biden improperly traded access while he served as vice president in President Barack Obama's administration. Biden denies the allegations.
"I write to you today because it is clear the House Republican impeachment is over," Siskel wrote. "The House Majority ought to work with the President on our economy, national security, and other important priorities on behalf of the American people, not continue to waste time on political stunts like this."
The letter reflects White House exasperation with House Republicans over what it views as a political stunt as Biden seeks re-election this year in a race against Republican former President Donald Trump.
"For over a year, House Republicans have been investigating President Biden in an effort to find something -- anything -- to hurt the President politically," Siskel wrote. "Instead, the investigation has continually turned up evidence that, in fact, the President did nothing wrong."
The timing of the letter also suggests the White House sees vulnerability for Johnson, whose majority in the chamber will slip to 218-213 next week when Congressman Ken Buck, a Republican who has criticized the impeachment inquiry, exits office early.
The president and Johnson were set to meet later on Friday at a reception on Capitol Hill.
