Russian President Vladimir Putin has asked Austria’s chancellor to organize a meeting with U.S. President Donald Trump in Vienna this summer and the White House is pondering the offer, a senior European official said.

Mr. Putin made the request during an official visit in the Austrian capital on Tuesday, the official said. Chancellor Sebastian Kurz accepted the request and pledged to approach Mr. Trump, the person said.

Mr. Putin’s entreaty suggests a summit between the U.S. and Russian leaders could happen sooner than expected just weeks ago. The Wall Street Journal reported last week that the White House had begun preliminary work on setting up a meeting between the two leaders. Jon Huntsman, the U.S. ambassador to Russia, was in Washington last week meeting with Trump administration officials to help arrange the summit, a senior administration official said.

“The Austrians have conveyed their willingness to host a meeting between President Trump and President Putin,” a U.S. National Security Council official said. “And, although the two leaders have previously discussed the possibility of arranging a meeting, we have nothing to announce at this time.”

The Kremlin didn’t respond to a request for comment on Thursday.
