Dem. Senator McCaskill nailed for falsely claiming she's never met with Russia's ambassador

Sen. Claire McCaskill took to Twitter on Thursday to slam Attorney General Jeff Sessions, her former colleague in the Senate, for failing to disclose having two meetings with Russian Ambassador Sergey Kislyak last year.

But McCaskill apparently went too far when she asserted that she had never once met with the Russian ambassador during her tenure on the Senate Armed Services Committee.

"I've been on the Armed Services Committee for 10 years," she wrote. "No call or meeting with Russian ambassador. Ever. Ambassadors call members of Foreign Relations Committee."

As National Review writer Charles C.W. Cooke points out, however, McCaskill twice talked about meetings with the Russian ambassador on her own Twitter feed -- once in 2013 and once in 2015.

McCaskill later clarified her claim to NBC News.

"[The meeting] was about adoptions... but it didn't have anything to do with Armed Services," she said. "And it was obviously not about the Russian ambassador it was about adoptions. The Russian ambassador has never called me as a member of the Armed Services Committee, he's never asked for a meeting with me, and I've never met with him one-on-one."
