President Donald Trump has sent a letter to House Speaker Nancy Pelosi promising to go forward with the State of the Union address scheduled for Tuesday.

Pelosi has insisted that the annual address to a joint session of Congress be postponed until the partial government shutdown is resolved.

The speaker of the House can prevent Congress from entering a joint session, increasing the likelihood that Trump will not get to deliver his speech on Tuesday.

WASHINGTON — President Donald Trump has informed House Speaker Nancy Pelosi he intends to go forward with the State of the Union address scheduled for Tuesday evening, extending the political game of chicken between the two leaders amid a partial government shutdown that appears to have no end in sight.

Pelosi followed up by informing Trump she would not allow a State of the Union to happen on Tuesday, setting up what could be a chaotic scene if the president follows through with his word.

In a letter to Pelosi on Wednesday afternoon, Trump wrote that he would show up to the House chamber on January 29, adding that "it would be so very sad for our Country if the State of the Union were not delivered on time, on schedule, and very importantly, on location!"

Trump also said that security for the event was not a concern, even though Pelosi raised the issue in her initial letter earlier this month calling for the speech's postponement.

But Trump may not be able to just show up and deliver the speech without Pelosi's blessing. The State of the Union address occurs during a joint session of Congress, which requires the consent of the speaker of the House to enter.

And later Wednesday, Pelosi responded to Trump in a letter stating that she will not take the procedural steps to convene a joint session of Congress.

"I am writing to inform you that the House of Representatives will not consider a concurrent resolution authorizing the President's State of the Union address in the House Chamber until government has opened," she wrote. "Again, I look forward to welcoming you to the House on a mutually agreeable date for this address when government has been opened."

Trump responded during a meeting at the White House, telling reporters he is "not surprised."

"It's really a shame what's happening with the Democrats," he added. "They've become radicalized."

Further, as speaker, Pelosi has control over the recording studio in the House, meaning she could have the cameras turned off inside the chamber. Because outside video cameras are not allowed into the chamber, there could be no broadcast of the event.

What could result Tuesday is a chaotic fight in the Democrat-controlled House. As Trump looks to take the spotlight, the already tense atmosphere could become much worse.

Democrats are already unnerved after Trump canceled the military chartered flight for a bipartisan delegation traveling to Afghanistan. When the group attempted to fly commercially, the White House leaked the travel plans, creating a security risk that resulted in the trip's cancelation, according to an aide to Pelosi (the White House denies this claim).

Pelosi had repeatedly called for postponing the address or having Trump submit it in writing, as was customary until President Woodrow Wilson delivered it in person in the early 20th century.
