Trump's legal team has also failed to gain any traction in Pennsylvania, which could certify its results by next week.
House Democrats said they would seek testimony from Emily Murphy, head of the General Services Administration. A Trump appointee, she has refused to allow Biden's team access to federal resources that are normally provided for a presidential transition.
"It is totally mystifying that the GSA refuses to make the statement necessary for the transition to happen in an orderly fashion," Pelosi told reporters.
Although Republican leaders have largely stood by as Trump seeks to overturn the election results, some GOP officials appeared to be running out of patience.
Rep. Fred Upton, R-Mich., one of the first elected Republicans to say he would work with Biden after his victory, said Friday he doubted that Trump could find a way to win his state.
"They're not going to make up 150,000 votes. I don't know what idea they have, they're going to elect different electors? The governor has to sign off on that, right?" he said.
Michigan Gov. Gretchen Whitmer, a Democrat, has been sharply critical of Trump.
Even though most of Trump's legal efforts have stalled, White House press secretary Kayleigh McEnany said in her first briefing since the election that Trump had no plans to concede.
"The president, again, is pursuing ongoing litigation, taking it day by day and we'll let that litigation play out," she said.
Vice President Mike Pence flew to Georgia to campaign for two Republican senators facing a runoff election next month. The outcome will determine which party controls the Senate, and Pence said the state "could be the last line of defense."
"We're going to keep fighting until every legal vote is counted," he said. "We're going to keep fighting until every illegal vote is thrown out."
