The Hill reports:

"An ethics lawyer under former President George W. Bush blasted Donald Trump Jr. for meeting with a Russian lawyer who claimed to have compromising information on then-Democratic presidential nominee Hillary Clinton during the campaign, saying it 'borders on treason.'

“'This was an effort to get opposition research on an opponent in an American political campaign from the Russians, who were known to be engaged in spying inside the United States,' Richard Painter said Sunday on MSNBC.

“"We do not get our opposition research from spies, we do not collaborate with Russian spies, unless we want to be accused of treason.'"
