Republicans draw the line with Trump on Russia

Conservatives suspicious of President Trump, along with other administration critics, have wondered if there's any line the president might cross that would meet resistance from the GOP Congress.

Gently but firmly, Congressional Republicans are rebuffing Trump on Russia.

Trump, an unconventional Republican with provocative communication habits, has faced few roadblocks from his more traditional, conservative allies. The Maginot Line appears to be Trump's apologetic, lenient approach toward Russia and strongman Vladimir Putin.

The resignation of Mike Flynn, Trump's national security advisor, partly over potentially improper contacts with Russia, has reinforced their resolve. Top Republicans are demanding an explanation, some even pushing for Congressional investigations while also using the situation to propose slapping Moscow with new economic sanctions.

"We're just being very realistic about the fact that Vladimir Putin is an adversary, and we have to stand up to him," Sen. John Hoeven, R-N.D., said in an interview with the Washington Examiner.
