Ted Cruz’s effort to tie United Nations funding to China’s abortion policy provoked a sharp, private rebuke from Mary L. Landrieu on the Senate floor Saturday morning.

Shortly before 4 a.m., the Louisiana Democrat strode from her desk on the Democratic side of the chamber all the way to the Texas Republican’s desk on the far side to give him a piece of her mind after Cruz insisted on a roll call vote on his amendment to the Senate budget resolution (S Con Res 8). Cruz wanted to create a new point of order against funding the United Nations as long as any of its member nations have a policy of involuntary abortions.

“I suggested to him that a more direct and a more effective route might be for Texas to stop all exports to China or to stop any financial exchanges between Texas and China,” Landrieu told CQ Roll Call after she voted on the budget shortly before 5 a.m.

“That would have had a much more direct effect on what he was trying to do than take money from the U.N. … I thought he might like the idea. He should try it next time,” Landrieu said.

After a cross-looking Landrieu left to return to her desk, a bemused Cruz smirked and chatted with Sen. Marco Rubio, R-Fla., who voted for the amendment.
