WASHINGTON (AP) — President Donald Trump says he’ll postpone his State of the Union address until the partial government shutdown ends, yielding after a weeklong showdown with House Speaker Nancy Pelosi.

House Speaker Nancy Pelosi served notice Wednesday that Trump wouldn’t be allowed to deliver the address to a joint session of Congress next week.

Fireworks over the speech shot back and forth between the Capitol and the White House as the monthlong partial government shutdown showed no signs of ending and about 800,000 federal workers faced the prospect of going without their second paycheck in a row come Friday.

Pelosi told Trump the House wouldn’t approve a resolution allowing him to address Congress until the shutdown ended. Trump shot back that Pelosi was afraid of hearing the truth.

“I think that’s a great blotch on the incredible country that we all love,” Trump said earlier Wednesday. “It’s a great, great horrible mark.”
