A group of Republican senators introduced legislation Wednesday that would require the State Department to certify the Palestinian Authority has ended its policy of paying families of terrorists.

“This bill stands for a simple principle: U.S. taxpayer dollars should never be used to fund terror against our own citizens or our ally Israel,” Arkansas Sen. Tom Cotton said in a statement. “The American people and the Israelis believe in helping the Palestinians build a better and more prosperous society. But that better society will never be possible if Palestinian leaders continue to funnel cash to terrorists and their families.
