A Republican lawmaker expressed shock and alarm over President Donald Trump's behavior during a joint press conference following his private meeting with Russian president Vladimir Putin.

Rep. Justin Amash (R-MI), the first sitting GOP lawmaker to float the possibility of impeachment, watched the nearly hourlong news conference with the same feeling of trepidation as many other Americans.

"A person can be in favor of improving relations with Russia, in favor of meeting with Putin, and still think something is not right here," Amash tweeted.

Trump met his Russian counterpart for more than two hours in Helsinki with only translators present, just three days after a federal grand jury indicted 12 Russian intelligence officers with hacking the 2016 election.

The president proclaimed that he trusted Putin's denials over the broad consensus of U.S. intelligence and law enforcement agencies, which he attacked from the news conference.
