McCain was scheduled to fly with 11 other senators and four House members on a military plane to the Munich Security Conference on Friday. But when he heard the flight had been pushed back to give the senators time to vote on Oklahoma Attorney General Scott Pruitt’s confirmation, he took matters into his own hands and booked a commercial flight departing Thursday night.

“I have been going to this conference for 40 years, and I told them months ago that I was going,” McCain told Politico.

“I have a speech to give tomorrow at the conference that I was committed” to, he said. “Everybody else is going after the vote.”

German Chancellor Angela Merkel, Vice President Pence and Defense Secretary James Mattis are all expected to attend the Munich Security Conference.

Pruitt is expected to make it through his confirmation vote with relative ease, even without McCain’s vote.
