President Trump may want House Speaker Nancy Pelosi (D-Calif.) to fly commercial, but first lady Melania Trump certainly doesn't have to.

After the speaker suggested she might rescind her invitation for Trump to deliver the State of the Union address, the president promptly shelved what he called her "public relations" trip to "Brussels, Egypt, and Afghanistan" scheduled for Thursday afternoon. Members of Congress usually use Air Force One for these trips.

Air Force One still took off that afternoon, but it didn't head overseas, Politico's Jake Sherman and aircraft-watching CivMilAir tweeted. It was using code that typically means the first lady is onboard, and it was headed for Mar-a-Lago's city of Palm Beach, Florida.

Pelosi hadn't announced her Congressional Delegation, or codel, trip before Trump issued the letter, in which he encouraged her to either "negotiat[e] with him" about the ongoing government shutdown or take a commercial flight to Afghanistan. Pelosi responded by saying her codel was stopping in Brussels to meet with "top NATO commanders, U.S. military leaders and key allies." She was also headed to Afghanistan to meet with troops and "obtain critical national security and intelligence briefings," adding that a stop in Egypt was never part of the plan.

As NPR's Kelsey Snell pointed out, codels are usually not publicly announced for security reasons, making Trump's "flying commercial" suggestion useless.
