Knew it. Warner's digging himself a really deep hole.

For example, Senator Mark Warner (D-VA) told CNN on Sunday that the U.S. government “does not know” what Trump and Putin discussed.
The media’s claim that this story amounts to a U.S. president concealing his secret discussions with the Russian president as part of his alleged collusion with Russia is fake news.
Senior U.S. officials knew exactly what was discussed in these meetings. This story is really about a successful effort by President Trump to prevent anti-Trump government officials from leaking sensitive national-security information to the press.
