President Joe Biden said he wasn’t surprised by the plane crash that appeared to kill the leader of a revolt against Vladimir Putin and he indicated the Russian president was behind it, writes dailymail.co.uk.

“I don’t know for a fact what happened but I"m not surprised”, - Biden said during his vacation at Lake Tahoe.

Biden spoke to reporters after he and his family had worked out at a Pelodog, a combination Pilates and cycle studio. He took a wrong turn coming out of the studio, having to double back to join his family and Secret Service detail.

And when asked if Putin was behind the crash of a plane where Wagner chief Yevgeny Prigozhin was listed as a passenger, Biden said he wasn"t sure and noted he had been working out for the past 90 minutes.

“There’s not much that happens in Russia that Putin’s not behind. But I don’t know enough to know the answer. I’ve been working out for the last hour and a half”, - he said.
