One Democrat Sinks His Party’s Iran War Powers Push Against President Trump

The Senate handed President Trump another win on Tuesday.

A Democrat-led war powers resolution meant to tie his hands on Iran failed to advance, falling one vote short.

The motion to discharge the resolution from committee went down 47-48.

The headline of the afternoon was who helped kill it.

Democrat John Fetterman of Pennsylvania voted no, lining up with most Republicans against his own party’s effort.

The resolution, S.J.Res.172, was the Warnock War Powers Resolution.

The Daily Caller reported that it would have directed President Trump to pull U.S. forces out of hostilities in Iran.

Four Republicans broke the other way and voted in favor: Bill Cassidy, Susan Collins, Lisa Murkowski, and Rand Paul.

The Daily Caller also noted that the House passed its own concurrent war powers resolution on June 3 by a 215-208 vote.

That House measure is largely symbolic and carries no legal force to bind President Trump.

So the Senate was the place that mattered, and the Senate said no.

The U.S. Senate Daily Press recorded the official floor update this way:

3:56 p.m. The Senate did not adopt the motion to discharge S.J.Res.172, Warnock War Powers Resolution from the Foreign Relations Committee, 47-48.

Five senators sat the vote out entirely: Michael Bennet, Cory Booker, Josh Hawley, Mitch McConnell, and Bernie Sanders.

The timing of the fight underlines how detached the resolution had become from events.

President Trump announced a diplomatic breakthrough on Sunday, with a 60-day ceasefire and the reopening of the Strait of Hormuz.

Some lawmakers were still pressing for more details about the deal as they tried to clip his authority.

That is the picture the vote left behind.

Democrats wanted to restrain a president who had just delivered a ceasefire and reopened one of the world’s most important shipping lanes.

They could not even hold their own caucus together to do it.
