Republican Rep. Will Hurd wrote in a New York Times op-ed that that President Donald Trump is participating in a disinformation campaign by Russian President Vladimir Putin.

The Texas Republican served as an undercover CIA officer before winning his first House race in 2014.

Hurd’s opinion piece comes after Trump’s meeting and news conference with the Russian president in Helsinki where he questioned the authority of his intelligence agencies and took Putin’s word that Russians didn’t meddle in U.S. elections.

“By playing into Vladimir Putin’s hands, the leader of the free world actively participated in a Russian disinformation campaign that legitimized Russian denial and weakened the credibility of the United States to both our friends and foes abroad,” Hurd wrote.

Hurd cited Russia’s efforts to hack into political organizations like the Democratic National Committee and the Democratic Congressional Campaign Committee and hack state election boards.
