WASHINGTON: Mike Pompeo took over as America’s top diplomat Thursday after being confirmed by the Senate and sworn in across the street minutes later. The new secretary of state immediately dashed off to Europe in an energetic start befitting the high-stakes issues awaiting him from Iran to North Korea.

The hard-charging former CIA director was confirmed on a 57-42 vote — one of the slimmest margins for the job in recent history.

Every past nominee to get a roll call vote since at least the Carter administration received 85 or more yes votes in the Senate, with the exception of Trump’s first secretary of state, Rex Tillerson, who got 56.

He was sworn in at the Supreme Court by Justice Samuel Alito, a fellow Italian-American, who said he was “proud” to officiate for the occasion. Pompeo, in a statement relayed by the State Department, said he was “delighted” to serve as America’s top diplomat.

“I am completely humbled by the responsibility and looking forward to serving the American people and getting to work right away,” Pompeo said.

Then it was off to Andrews Air Force Base, where a government aircraft was waiting to ferry him to Brussels for meetings at NATO headquarters.

State Department staffers, demoralized after a tumultuous first year of President Donald Trump’s administration, gave a round of applause to Pompeo, who responded as he boarded the aircraft with a casual, “Hi, I’m Mike.”

His confirmation creates a vacancy atop the CIA that will be filled, at least for now, by Gina Haspel, the intelligence agency’s No. 2 official. Trump has nominated Haspel to replace Pompeo.
