Re the 60 days. Trump has spoken about it. From the CNN feed:
"President Donald Trump on Thursday complained about congressional efforts aimed at limiting his war powers — the latest of which the Senate rejected this afternoon.
“They go again and again on the war power,” Trump told reporters in the Oval Office. “I’m negotiating a deal with Iran,” he added. “And every week, every three days, they put in a thing that the war should stop.”
A post-Vietnam War law puts a 60-day clock on the use of military force without congressional authorization. The Iran war would hit that 60-day mark on May 1, according to the text of the law, the War Powers Resolution, but there’s some confusion in Congress over the exact date of the deadline.
Some lawmakers say the 60-day clock started from the date hostilities began, which would make the deadline April 29, while others cite the text of the law to argue it’s 60 calendar days from the date the White House officially notified Congress, which would put the deadline at May 1. Other Republicans argue that ceasefire days don’t count towards the 60-day total, or say that the president can unilaterally extend the deadline to 90-days."
For a man that claims to know more about almost everything than anyone else, he sure does struggle with specifics.
