MSNBC Guest: Trump's Warsaw Speech 'Fulfillment of Bin Laden's Ideology'

Charles Krauthammer said that people in President Trump's orbit have an "epidemic of amnesia having to do with the Russians."

Krauthammer said that of the three people in the meeting with Natalia Veselnitskaya - Donald Trump Jr., Paul Manafort and Jared Kushner - no one remembered anything until now.

Krauthammer said Trump Jr. is similar to Bill Clinton, in that he has an "approximate approach to the truth."

"As if, saying it is a last resort," Krauthammer said, adding that the president's son gave three explanations for the meeting.

The final explanation, he said, was the most believable.

According to Krauthammer, Trump Jr. said that Veselnitskaya announced she had what amounted to opposition research on Hillary Clinton.

But, when the meeting took place, Veselnitskaya offered nothing of the sort, other than to ask that Trump Sr. work on restoring the acceptance of Russian children as adoptees in the United States.
