A week after North Korea claimed a hydrogen bomb test, U.S. lawmakers are pushing for new sanctions.

FOX's Jared Halpern has more from Capitol Hill:

Despite tough sanctions already leveled on the rogue regime... A bipartisan measure in Congress aims to tighten the screws even further:

(Royce) "A return to the strategy of effective financial pressure on North Korea is our best bet."

House Foreign Affairs Committee chairman Republican Ed Royce's legislation would go after hard currency North Korea gets through illicit and counterfeit trade and sanction anyone discovered to be doing business with the country.

Despite strong House support from both sides of the aisle, it's not clear how soon the Senate may act.
