Republican Senator Pat Toomey and Democrat Chris Van Hollen offered the “Otto Warmbier Banking Restrictions Involving North Korea (BRINK) Act” days after a summit between Republican President Donald Trump and North Korean leader Kim Jong Un was abruptly cut off after they failed to reach a deal for the reclusive communist nation to give up its nuclear weapons.

After the summit, Trump said he believed Kim’s claim not to have known how Otto Warmbier was treated, prompting his parents to issue a sharp statement strongly condemning Kim’s “evil regime” and blaming it for their son’s death.

In a statement, Fred and Cindy Warmbier thanked van Hollen and Toomey, and said they believed the legislation would provide useful tools to help change North Korea.

“We continue to support the bill and appreciate them honoring our son’s memory,” the Warmbiers said.
