Democratic Senators are expected to introduce legislation as early as Monday that aims to overturn President Trump's executive orders on immigration.
On Sunday, Sen. Chris Murphy, D-Conn., announced via Twitter that he was planning a bill "this week" that would put a stop to what he called Trump's "dangerous, hateful order."

On Monday morning, Murphy told MSNBC that Trump's ban would encourage terrorist recruitment by positioning the United States as anti-Muslim: "This, ultimately, is going to get Americans killed. I believe it."
"We have now handed them a path to rebirth...this is a huge win for hardliners," Murphy said of ISIS cells in the Middle East.
He also stressed that the U.S. should retain a program for refugees escaping ISIS: "We are not a partner in fighting ISIS if we are not a partner in trying to deal with the flow of displaced peoples outside of those countries."
