UPDATE: After exchanging letters earlier on Wednesday with House Speaker Nancy Pelosi in which he said he would give his State of the Union Address in the Capitol next Tuesday as originally planned and she countered that she would not allow him to give the speech in the House chamber until the shutdown was over, President Donald Trump issued two Tweets after 11:00 pm Eastern time on Wednesday night effectively conceding defeat by saying he will deliver his State of the Union after the shutdown is over.

"I will do the Address when the shutdown is over," Trump said in the first Tweet.

"I am not looking for an alternative venue for the SOTU Address because there is no venue that can compete with the history, tradition and importance of the House Chamber," he said as the message continued into a second Tweet.

"State of the Union Address in the near future," he said--presuming, apparently, that the shutdown will end in the near future.

Here are the Tweets:

(CNSNews.com) - President Donald Trump sent a letter to House Speaker Nancy Pelosi today saying that he would honor her original invitation, made in a Jan. 3 letter, to deliver his State of the Union Address in the chamber of the House of Representatives on Tuesday, Jan. 29.

Pelosi quickly responded with a letter to Trump. It said: No you won’t.

“I look forward to seeing you on the evening on January 29th in the Chamber of the House of Representatives. 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 said in his letter.

“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,” Pelosi wrote in her response.

Below are the full texts for both Trump’s and Pelosi’s letters.

President Donald Trump’s Jan. 23 letter to House Speaker Nancy Pelosi:

The Honorable Nancy Pelosi

Speaker of the House of Representatives

Washington, D.C. 20515

Dear Madam Speaker:

Thank you for your letter of January 3, 2019, sent to me long after the Shutdown began, inviting me to address the Nation on January 29th as to the State of the Union. As you know, I had already accepted your kind invitation, however, I then received another letter from you dated January 16, 2019, wherein you expressed concerns regarding security during the State of the Union Address due to the Shutdown. Even prior to asking, I was contacted by the Department of Homeland Security and the United States Secret Service to explain that there would be absolutely no problem regarding security with respect to the event. They have since confirmed this publicly.

Accordingly, there are no security concerns regarding the State of the Union Address. Therefore, I will be honoring your invitation, and fulfilling my Constitutional duty, to deliver important information to the people and Congress of the United States of America regarding the State of our Union.

I look forward to seeing you on the evening on January 29th in the Chamber of the House of Representatives. 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!

Sincerely,

Donald J. Trump

House Speaker Nancy Pelosi’s Jan. 23 letter to President Donald Trump:

The President

The White House

1600 Pennsylvania Avenue, Northwest

Washington, D.C. 20500

Dear Mr. President:

When I extended an invitation on January 3rd for you to deliver the State of the Union address, it was on the mutually agreed upon date, January 29th. At that time, there was no thought that the government would still be shut down.

In my further correspondence of January 16th, I said we should work together to find a mutually agreeable date when government has re-opened and I hope that we can still do that.

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.

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

Sincerely,

Nancy Pelosi
