President Donald Trump told his administration's envoys to stop talks with Iran on Tuesday, CNN reported.

CNN anchor Jake Tapper reported that Trump officials have told allies that they have shifted their strategy from "hammer Iran ASAP" to "strangle them over time," according to sources.

Lawmakers have shared their concerns amid reports of dwindling weapon supplies and low morale among troops as the military operations have continued for nearly six months.

Sen. Richard Blumenthal (D-CT), who serves on the Senate Armed Services Committee, reacted to the administration's reported change in an interview with Tapper.

"I think it's another indication that he has reached a strategic dead-end," Blumenthal said. "He has involved this nation in a seemingly endless, costly war. Just as the [USS] Abraham Lincoln is on an endless, seemingly indefinite deployment with no exit. The idea that he would 'strangle Iran' seems pretty magical thinking."

He called out Trump for lack of strategy and cost of the war — from gas, groceries and worldwide economic backlash.

"He's playing a dangerous game of chicken," Blumenthal added.
