In reading the headline, my first impressions was that after Trump's strike on Syria they want to tie his hands.
"...legal basis for military action against terrorist groups..." So ... they not only want to tie his hands, but they also want to ensure that the invasion over our porous borders continues as well as ensuring that we keep the border open with open arms ....
Then I read who also is supporting the bill ... Kaine, Flake, Coons, Young and Nelson, and I have no doubt that the leftist mental midgets want to tie his hands.
