President Barack Obama sees himself as a “monarch” or “emperor” who can ignore Congress and do whatever he wants, says Republican Sen. Marco Rubio.

Obama violated the law, Rubio said, when he failed to give 30 days’ notice to Congress before releasing five Taliban prisoners from the military prison at Guantanamo Bay in exchange for Army Sgt. Bowe Bergdahl on Saturday.

“The law is very clear. He must give congressional notification 30 days before any prisoner in Guantanamo is released,” Rubio told Fox News’ Gretchen Carlson on Tuesday. “He failed to do that.”

“Apparently the only person he told was [Senate Majority Leader] Harry Reid,” Rubio said. “He didn’t even tell the chairwoman of the Intelligence Committee, a Democrat, Dianne Feinstein.”

Feinstein has expressed her displeasure at not being notified, as have Republicans in the House and Senate.
