Republican unloads on Trump for missing deadline to hold Putin accountable for poisonings

A spate of mysterious poisonings in Britain has been linked to the Kremlin—yet so far, President Donald Trump has failed to commit to holding Russia accountable by enforcing sanctions.

Even Republicans are wary of the administration's inaction. On Thursday, NBC obtained a letter by Rep. Ed Royce (R-CA) chastising the White House for delaying a decision on whether to ramp up sanctions.

“In recent years, Vladimir Putin has steadily escalated his campaign to consolidate power and undermine the United States,” Royce said in the letter.

“Your compliance with the Chemical and Biological Weapons and Warfare Elimination Act of 1991 is critical to showing Putin that we are serious about challenging his deadly acts, as well as his ongoing attacks on our democracy.”

Royce also pointed out that based on the statutory deadline the Trump administration should have acted more than a month ago.

The letter comes as Donald Trump's one-on-one meeting with President Putin continues to draw criticism from Democrats and Republicans alike.
