The member is Tulsi Gabbard, Dem-Hi, and she is pretty damn impressive. She served, Army I think in the ME, and does not take crap from anyone. The dems kicked her off some prestigious DNC committee when she backed Bernie instead of Hillary. Trump had her up to the interview room a couple of weeks ago. If he made her Sec. of State, I would applaud.
Her bill might be a bit of signaling to Trump, but until he came in, it had no chance. Influential republicans like those morons McCain and Graham wanted to invade Syria, not get uninvolved. And Obama wasn't accepting any limits on giving arms to muslim terrorists. It's practically his main legacy.
