Secretary of State Rex Tillerson Rex Wayne TillersonGary Cohn: 'I haven't made up my mind' on vote for president in November Kushner says 'Alice in Wonderland' describes Trump presidency: Woodward book Conspicuous by their absence from the Republican Convention MORE will travel to Europe next week to meet with key NATO allies, the State Department announced on Thursday as reports indicate he could soon be leaving his post.

Tillerson will travel to Brussels, Vienna and Paris, spokeswoman Heather Nauert said in a statement.

Tillerson will meet with the European Union's chief diplomat, Federica Mogherini, and NATO Secretary General Jens Stoltenberg during the trip to Brussels. He will also take part in NATO’s foreign ministers meeting.

Mogherini traveled to Washington, D.C., earlier this month to defend the Iran nuclear deal, which was negotiated between the U.S., Iran and international powers. President Trump last month chose to decertify the accord, which provided Tehran with sanctions relief in exchange for curbs to its nuclear program.

Trump's decision to decertify the nuclear accord did not entirely kill the deal, but provided Congress with a 60-day window to reinstate sanctions that were previously lifted on Tehran. Trump in his October announcement did not call for the reinstatement of nuclear sanctions.

“It’s belonging to the entire international community and as Europeans, we’ll make sure it stays, Mogherini told CNN’s Christiane Amanpour while in Washington.

While in Vienna, Tillerson will attend a conference hosted by the Austrian foreign minister. He will then head to Paris for talks about the Middle East region, North Korea, and the Sahel, according to Nauert.
