Donald Trump released a letter on Thursday stating that he is canceling Speaker Nancy Pelosi’s planned international travel in response to her request to postpone the State of the Union address due to the government shutdown.

In a letter to Pelosi, Trump told her a congressional delegation trip she intended to take to Brussels, Egypt and Afghanistan “has been postponed.”

The president dismissed the trip as a “public relations event,” and said if she wants to go by flying commercial, “that would certainly be your prerogative.”

“I also feel that, during this period, it would be better in Washington negotiating with me and joining the Strong Border Security movement to end the shutdown,” he wrote.

Sarah Huckabee Sanders tweeted out the letter, “President @realDonaldTrump’s letter to @SpeakerPelosi concerning her upcoming travel”

The response comes one day after Pelosi requested Trump move his address from its scheduled date on Jan. 29, citing security concerns related to the record-long shutdown.

The president did not address the Speaker’s request to move the date of his speech.

There was speculation on Capitol Hill that Pelosi’s trip may have already been canceled when congressional leaders scrapped next week’s recess.

Pelosi hasn’t responded, but Majority Leader Steny Hoyer says Trump’s decision is “petty and ridiculous.”

House Majority Leader Hoyer says President Trump's decision to postpone Speaker Pelosi's foreign trip via military aircraft is “petty and ridiculous."

UPDATE:

Pelosi’s rep has now responded:

The CODEL to Afghanistan 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. (1/4)

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. (3/4)

This is cute but the House cancelled its recess next week so presume this trip was already cancelled.

Trump thinks he's playing chess but he's really playing Hungry Hungry Hippos https://t.co/WxLsTtxI97

Pelosi took from Trump one of the most visible rhetorical tools of the modern presidency.

Trump took from Pelosi a perk — if you can call a military flight to Afghanistan a perk — that few people know or care about. And it feels petty.

Advantage: Pelosi. https://t.co/TpZJYxvnRx
