Sen. Chris Murphy (D-CT) pushed back on criticisms of President Joe Biden‘s plan to limit certain weapons shipments to Israel, arguing that the U.S. has “no obligation” to hand a “blank check” to allies.

Murphy was asked specifically about Sen. John Fetterman’s (D-PA) critique of Biden’s threats to Israel if they move forward with an operation in Rafah. On CNN’s State of the Union on Sunday, Murphy defended the U.S. strategy.
