ROUGH CUT (NO REPORTER NARRATION) U.S. President Donald Trump said on Wednesday he would do an alternative event to the State of the Union address after House Speaker Nancy Pelosi told him he may not give the speech in the House of Representatives until the government shutdown is over.

The clash between two of Washington's most powerful leaders represented an escalation in a standoff that has resulted in a 33-day partial government closure that threatens the U.S. economy and the livelihoods of 800,000 federal workers.

On Pelosi's move to lock him out of the House, Trump said at a White House meeting on border security, "It's a disgrace." Pelosi told the president that for now she would not consider a measure authorizing the speech, an annual, televised rite in American politics traditionally delivered in the House chamber.

"Again, I look forward to welcoming you to the House on a mutually agreeable date for this address when government has been opened," Pelosi said to Trump in a letter.

Earlier in the day, Trump essentially dared her to disinvite him from making the speech, which was set for Jan.

The State of the Union speech, used by presidents to announce their policy goals for the year, has become a hostage to the showdown between Trump and congressional Democrats over his demand for money for a U.S.-Mexico border wall.
