Speaker Nancy Pelosi (D-Calif.) during a speech at the Conference of Mayors on Wednesday night pleaded with the Republicans in attendance, “Take back your party.”

“To the Republicans in the crowd, I say: take back your party, the Grand Old Party,” Pelosi said the annual gathering of U.S. mayors. “America needs a strong Republican Party, not a rubber stamp.”

Pelosi’s comments came on the 33rd day of the ongoing partial government shutdown, which became the longest in U.S. history almost two weeks ago. White House negotiators and Democratic leaders have been at an impasse over Trump’s demand for $5.7 in border wall funding, which Democrats have refused to provide.
