Since many of my Democrat colleagues don’t seem to understand the War Powers Act, it’s very simple:

The President must notify Congress within 48 hours of deploying troops or commencing an attack.  - Mike Lawler@lawler4ny

• The President must then withdraw troops within 60-90 days, unless Congress declares war. 
• In this instance, Congress was notified in advance and briefed before the strike on Iran... 
• Now, Congress can pass a concurrent resolution ordering the troops be withdrawn at anytime, which is what Massie and Khanna are trying to do. 
• But under Article II and as Commander in Chief, the President has the authority to act. 

The notion that this strike is illegal or that the President needed Congress’ authority is wrong. Furthermore, Biden and Obama conducted numerous strikes in numerous countries without Congress and none of the people screaming now, seemed to have any objections. 

• For historical context, Congress has not declared war since WWII.
