WASHINGTON — She imperiled his State of the Union address. He denied her a plane to visit troops abroad.

The shutdown battle between President Donald Trump and House Speaker Nancy Pelosi is playing out as a surreal game of constitutional brinkmanship, with both flexing their political powers from opposite ends of Pennsylvania Avenue as the negotiations to end the monthlong partial government shutdown remain stalled.

In dramatic fashion, Trump issued a letter to Pelosi on Thursday, just before she and other lawmakers were set to depart on the previously undisclosed trip to Afghanistan and Brussels. Trump belittled the trip as a "public relations event" — even though he had just made a similar warzone stop — and said it would be best if Pelosi remained in Washington to negotiate to reopen the government.

"Obviously, if you would like to make your journey by flying commercial, that would certainly be your prerogative," wrote Trump, who had been smarting since Pelosi, the day before, called on him to postpone his Jan. 29 State of the Union address due to the shutdown.

Denying military aircraft to a senior lawmaker — let alone the speaker, who is second in line to the White House, traveling to a combat region — is very rare. Lawmakers were caught off guard. A bus to ferry the legislators to their departure idled outside the Capitol on Thursday afternoon.

The political tit-for-tat between Trump and Pelosi laid bare how the government-wide crisis has devolved into an intensely pointed clash between two leaders both determined to prevail. It took place as hundreds of thousands of federal workers go without pay and Washington's routine protocols — a president's speech to Congress, a lawmaker's official trip — became collateral damage.

Pelosi spokesman Drew Hammill said the speaker planned to travel to Afghanistan and Brussels to thank service members and obtain briefings on national security and intelligence "from those on the front lines." He noted Trump had traveled to Iraq during the shutdown and said a Republican-led congressional trip also had taken place.

Trump's move was the latest example of his extraordinary willingness to tether U.S. government resources to his political needs. He has publicly urged the Justice Department to investigate political opponents and threatened to cut disaster aid to Puerto Rico amid a spat with the island territory's leaders.
