Texas Republican and former CIA officer, Rep. Will Hurd, writes in a New York Times op-ed that President Trump "actively participated in a Russian disinformation campaign" while meeting with Russian President Vladimir Putin in Helsinki this week.

Why it matters: Lawmakers are still reeling from Trump's show of solidarity with the Russian president. But Republicans are split — while many in the GOP found Trump's joint-conference with Putin "unexplainable, unacceptable and un-American," according to Axios' Mike Allen and Jonathan Swan, few will do anything about it. But, Republican voters approved of the summit overwhelmingly (79%).

"Over the course of my career as an undercover officer in the C.I.A., I saw Russian intelligence manipulate many people. I never thought I would see the day when an American president would be one of them."

"Somehow many Americans have forgotten that Russia is our adversary, not our ally...For more than a decade, Russia has meddled in elections around the world, supported brutal dictators and invaded sovereign nations — all to the detriment of United States interests."

"I hope the president shares my conviction that American strength, not weakness, is the best way to preserve a secure world in the face of adversaries like Russia."
