This is the longest shutdown in US history

House Speaker Nancy Pelosi’s spokesperson has refuted some of what President Trump said about the trip in his letter to her.

Her spokesperson Drew Hammill said in a series of tweets that the military aircraft that was supposed fly a congressional delegation to Afghanistan this weekend, "included a required stop in Brussels for pilot rest."

"In Brussels, the delegation was scheduled to meet with top NATO commanders, U.S. military leaders and key allies–to affirm the United States’ ironclad commitment to the NATO alliance," Hammill tweeted.

The trip to Afghanistan, he said, did not include a stop in Egypt. (Trump said Pelosi was headed to Egypt in his letter.)

Pelosi's spokesperson went on to said that "the purpose of the trip was to express appreciation & thanks to our men & women in uniform for their service & dedication, & to obtain critical national security & intelligence briefings from those on the front lines."

Two Trump administration officials say the trip to Davos for the World Economic Forum is still on.

It is scheduled for next week, Jan. 22 to 25.

President Trump canceled his appearance at the forum because of the ongoing government shutdown. Instead, Treasury secretary Steven Mnuchin will lead the delegation. Here's who else is going:

White House officials, including acting chief of staff Mick Mulvaney, began discussing potentially canceling House Speaker Nancy Pelosi’s trip early this morning, according to two people with knowledge of how things unfolded.

They felt completely caught off guard when Pelosi publicly released her letter calling on President Trump to postpone his State of the Union address, or deliver it in writing.

Trump has been frustrated by coverage of the shutdown — at times asking why it seemed that the Democrats had the upper hand since he felt they did — and aides agreed this would be the perfect response. 

Despite a White House official telling the pool this was not a response to Pelosi, another official made clear it is “retaliation.” 

Republican Sen. Lindsey Graham condemned the letter exchange between President Trump and Speaker of the House Nancy Pelosi.

Graham called Pelosi's letter to President Trump asking he move the date of his State of the Union address "very irresponsible and blatantly political." He also called Trump's letter to Pelosi denying her military aircraft for an upcoming overseas trip "inappropriate."

"I wish our political leadership could find the same desire to work for common goals as those who serve our nation in uniform and other capacities," he wrote in another tweet in the series.

Here are some of his tweets:

Rep. Mark Meadows, President Trump's close ally and a conservative Republican from North Carolina, told CNN he thinks Trump will give his State of the Union address “somewhere else” and said this will hurt Speaker of the House Nancy Pelosi.

Meadows, chairman of House Freedom Caucus, also said Trump is “not backing down” over the wall.

“And each one of our districts has to weigh in on that. And national polls do not necessarily reflect what's happening in our districts. I can tell you that border barriers and making sure that there's a compromise, I can tell you what, my district, both moderates, liberals and conservatives are saying that there should be a compromise," he said.

House Majority Leader Steny Hoyer told CNN that “it demeans the Presidency” for President Trump to have denied military aircraft for House Speaker Nancy Pelosi’s trip so abruptly.

He said the move was “so petty.”

What happened: President Trump today wrote a letter to Pelosi informing her that he was canceling the military aircraft she would have used in an upcoming trip to Brussels, Egypt and Afghanistan because of the shutdown.

Pelosi was scheduled to leave for her trip this afternoon, two White House officials told CNN.

Trump's actions come one day after Pelosi asked the President to find a new date for his State of the Union address due to the ongoing shutdown. 

House Speaker Nancy Pelosi was scheduled to leave this afternoon when President Trump canceled use of the military aircraft, two White House officials said.

 Another source said she is still at the Capitol but was supposed to depart this afternoon.

 The administration "worked with the Air Force and DOD and basically took away the rights to the plane from the speaker." 

This official argued that Pelosi's trip would have "guaranteed" that federal workers would not get a paycheck since she would have been out of the country — even though there is no deal currently on the table for those paychecks to go out.

President Trump just wrote a letter to House Speaker Nancy Pelosi denying her military aircraft for an upcoming overseas trip.

The President of the United States does have the authority to direct the Department of Defense to not use military assets to support a congressional delegation to military theaters. This support includes air transport and additional security procedures. 

However, it was not immediately clear whether the Department of Defense was notified of the decision prior to the President’s announcement. 

In apparent tit-for-tat, President Trump sent a letter to Speaker of the House Nancy Pelosi canceling her trip to Brussels, Egypt and Afghanistan during the shutdown.

The President's letter comes a day after Pelosi sent a letter to Trump asking him to move the date of his State of the Union speech due to security staffing concerns during the shutdown.

Read Trump's full letter below:

Dear Madame Speaker,

Due to the Shutdown, I am sorry to inform you that your trip to Brussels, Egypt, and Afghanistan has been postponed. We will reschedule this seven-day excursion when the Shutdown is over. In light of the 800,000 great American workers not receiving pay, I am sure you would agree that postponing this public relations event is totally appropriate. I also feel that, during this period, it would be better if you were in Washinton negotiating with me and joining the Strong Border Security movement to end the Shutdown. Obviously, if you would like to make your journey by flying commercial, that would certainly be your prerogative.

I look forward to seeing you soon and even more forward to watching our open and dangerous Southern Border finally receive the attention, funding, and security it so desperately deserves!

Sincerely,

Donald J. Trump
