Senate Democrats failed in their attempt to limit President Donald Trump's ability to order a military strike on Iran.

Here's what we know

Sens. Time Kaine (D-Va.) and Tom Udall (D-N.M.) introduced an amendment to the National Defense Authorization Act to "prohibit unauthorized military operations in or against Iran."

Since Democrats only currently have 45 seats in the Senate (plus 2 Independents who caucus with Democrats), they would have needed 13 Republicans to break ranks in order to get the 60 votes needed for the amendment to pass. Only four Republicans did: Susan Collins (R-Maine), Mike Lee (R-Utah), Jerry Moran (R-Kan.), and Rand Paul (R-Ky.).

"None of our Democratic friends would be supporting this if there was a Democratic president," McConnell said, according to the Hill. "This is clearly within the bounds of measured response that have not been micromanaged by Congress in the past." He said that the motivation behind the amendment was "Trump derangement syndrome."

Kaine said that he thought it was "important that everybody be on the record of this." He added "we could not let the NDAA go by, when we were 10 minutes away from a war, without having the discussion or the troops and the public would have said 'what the hell were you guys doing?'

Kaine was referring to Trump's initial claim on Twitter on June 21 that he had decided not to launch a retaliatory strike against Iran "10 minutes before" it was supposed to take place, once he had been made aware of the number of casualties that would ensue. He would later say that he had called off the strike "half an hour" before it would have happened. This had been in response to Iran shooting down an unmanned U.S. drone.
