"We just have too much at stake in this election to sit on the sidelines and be silent while we still have time to do something," Scholten told the Detroit News on Thursday.
Scholten said the decision to run is Biden's alone but urged him to drop out of the race, saying he must do so "for the good of the democracy."
Though Scholten praised Biden's political legacy, she said her top concern is about governance. Scholten said that the American people can no longer ignore Biden's poor debate performance two weeks ago and her constituents' confidence in his leadership is shaken.
The congresswoman is the first lawmaker from the battleground state to urge Biden to abandon his campaign.
Three other congressional Democrats joined her plea on Thursday: Brad Schneider of Illinois, Greg Stanton of Arizona, and Ed Case of Hawaii. At least nine other House Democrats and one Senate Democrat have publicly called on Biden to step aside.
"This has nothing to do with his character and record. If it did, there would be no decision to make. This is solely about the future, about the President's ability to continue in the most difficult job in the world for another four-year term," said Case in a statement.
The statements come as President Biden prepares for a news conference Thursday evening to dispel doubts about his leadership ability.
Unless he drops out, Biden is expected to be renominated in six weeks at the Democratic National Convention in Chicago on August 19-22.
