House Minority Leader Nancy Pelosi said Wednesday that Republicans have "no excuse" to shut down the government under their watch since they control both the White House and Congress.

"With a Republican House, Senate and Administration, Republicans have absolutely no excuses for threatening America's families with a destructive and pointless government shutdown," the California Democrat said in a statement.

Her comment comes after President Trump on Tuesday night threatened a government shutdown over funding for his border wall after the crowd began chanting, "Build that wall!"

"Build that wall," Mr. Trump said. "Now the obstructionist Democrats would like us not to do it. But believe me, if we have to close down our government, we're building that wall."

But Democrats, Pelosi reiterated, would never support funding for the wall, which the president had originally promised would be paid for by Mexico.

"President Trump's multi-billion dollar border wall boondoggle is strongly opposed by Democrats and many Republicans," Pelosi said. "Democrats will stand fast against the immoral, ineffective border wall and the rest of Republicans' unacceptable poison pill riders."
