A Trump administration official said the president still intends to deliver that speech on January 29, even though House Speaker Nancy Pelosi, the top U.S. Democrat, had recommended he delay it, citing concerns about security for the event with some personnel furloughed during a monthlong shutdown.
Trump and Pelosi have been embroiled in an intense showdown over the partial government shutdown, which began shortly before the Christmas holiday, over Congress' inability to pass a spending package that includes the $5.7 billion Trump has claimed is necessary to construct a "wall" along the U.S. -Mexico border.
Cory Gardner is the latest to confirm he would support the Democrat-backed "clean funding bill", which does not include any money for Mr Trump's US-Mexico wall.
The partial USA government shutdown began on December 22, 2018.
"This is her prerogative - I will do the Address when the Shutdown is over", said Trump.
The drama started on January 16, when Pelosi sent a letter to Trump informing him that, because of the partial government shutdown, he should postpone the State of the Union, which had been scheduled for January 29 in the Capitol. Actually, most of the country likely would prefer he give it in writing.
Declaring there are "no security concerns", Trump said he planned to fulfill his "Constitutional duty" to report to Congress on the state of the union.
A president can not speak in Congress unless he is invited by the Speaker of the House.
Trump announced plans for an "alternative" to the annual event, set for January 29, in which the president highlights his administration's successes, as well as plans for the future, in a statement Wednesday.
"In our risk-averse industry, we can not even calculate the level of risk now at play, nor predict the point at which the entire system will break", NATCA president Paul Rinaldi said in a statement.
First Lady Melania Trump is inviting her guests as every first lady does, Conway said, and hoped that the speaker will not deny seats to her guests.
"I would have done it in a different location but I think that would be very disrespectful to the State of the Union", Trump said Thursday.
Jedediah Bila said that Pelosi was being overtly "spiteful" to Trump, who has not relinquished his demand for increased border security in exchange for an end to the partial shutdown.
Republican Representative Tom Cole, a member of the House Appropriations Committee, told reporters the Democratic proposal could help.
During the 2016 presidential campaign, Trump promised that Mexico would pay for his wall, but Mexico refused and now the Republican president wants United States taxpayers to pay for it.
Mrs Pelosi has said she's not budging until the government reopens - and in this particular case, her word is final.
"All of us believe that if we had three weeks with the government open, with all the discord coming from a shutdown, that we could find a way forward to produce a bill that he would sign", Graham said on the Senate floor.
The Department of Homeland Security later cast those concerns aside, saying its agents and officers had been preparing for months to protect the venue, and would be ready shutdown or not.
Responding to questions, she appeared to be against Trump holding a rally somewhere else in the country instead of the State of the Union.
Pelosi's moves have left the White House scrambling to devise an alternative plan for the speech, which is one of the president's top opportunities to lay out his agenda to the public.
