A bipartisan group of nearly 40 members of Congress is requesting Secretary of State Antony Blinken to provide “immediate classified briefings” on “Turkey’s growing relationship with Hamas.”

The letter, led by Reps. Josh Gottheimer (D-NJ), Gus Bilirakis (R-FL), Dan Goldman (D-NY), and Nicole Malliotakis (R-NY) and co-signed by 34 other representatives in the House, is meant to raise “serious concerns” about whether Turkey, a NATO member, is aiding the terrorist group Hamas.
