Before the culprits in the Paris terrorist attacks were even identified, senators with big 2015 and 2016 ambitions were already rushing to file legislation to respond. Thursday, as the House of Representatives likely pushes through legislation to increase the security of refugee resettlement, a growing number of Republicans are introducing even tougher bills.

Rep. Mike McCaul (R-Tex.): The American Security Against Foreign Enemies Act of 2015
The official vehicle of the House Republicans, which would add new layers to refugee background checks. Among them are "a thorough background investigation" by the FBI, an analysis by the Department of Homeland Security, and a monthly report on who's been let in. The refugees covered include anyone who "has been present in Iraq or Syria at any time on or after March 1, 2011."

Sen. Ted Cruz (R-Tex.): The Terrorist Refugee Infiltration Prevention Act of 2015
Introduced Wednesday night, Cruz's bill is written to block any refugee who is "a national of, has habitually resided in, or is claiming refugee status due to events in" a country with substantial territory controlled "by a Foreign Terrorist Organization, as designated by the State Department." Cruz's much-criticized (but potentially popular) exception for Christians is intended to be covered by a line allowing a refugee to enter the United States if he "is a member of a group that has been designated by the Secretary of State or by an Act of Congress as a victim of genocide."

Sen. Rand Paul (R-Ky.): an amendment to the Transportation, Housing, and Urban Development Appropriations Act
Rolled out Monday — before Cruz's bill, as Paul's team would be first to point out — this bill would prohibit any funds being used to "provide or administer assistance to aliens admitted" from any of the following nations: Afghanistan, Algeria, Bahrain, Bangladesh, Egypt, Eritrea, Indonesia, Iran, Iraq, Jordan, Kazakhstan, Kuwait, Kyrgyzstan, Lebanon, Libya, Mali, Morocco, Nigeria, North Korea, Oman, Pakistan, Qatar, Russia, Saudi Arabia, Somalia, Sudan, Syria, Tajikistan, Tunisia, Turkey, United Arab Emirates, Uzbekistan, Yemen, and "the Palestinian Territories."

Sen. David Vitter (R-La.): The Syrian Refugee Verification and Safety Act of 2015
Vitter, who has been lagging far behind in his race for governor of Louisiana, quickly seized on the issue of refugee resettlement and pledged to stop it if elected. (There are serious legal questions about whether that's even possible). His bill would "suspend the admission and resettlement of aliens seeking refugee status because of the conflict in Syria until adequate protocols are established to protect the national security of the United States." Unlike Paul, Vitter does not delineate the countries affected; unlike Cruz, he does not provide an exception for any specific group of people. And while the legislation establishes a multi-stage process by which the Obama administration could prove that it is vetting refugees, it would subject its proof to a congressional disapproval vote. Vitter also asks for "the identity of the aliens admitted to the United States as refugees since 2001 who subsequently engaged in criminal or terrorist conduct."

Rep. Ted Yoho (R-Fla.): The Give States a Chance Act of 2015
A short attempt to fix the potential legal issues with the mass revolt of governors against refugee resettlement; it would "authorize the Governor of any State in which it is proposed to place or resettle a Syrian refugee to refuse such placement or resettlement if the Governor makes certain certifications."

Rep. Brian Babin (R-Tex.): The Refugee Resettlement Accountability National Security Act of 2015
The Texas freshman's legislation predates the current panic by four months, and would prevent the admission of any "alien under section 207 of the Immigration and Nationality Act (8 U.S.C. 1157) until such time as Congress passes a joint resolution giving the Secretary authority to resume admitting aliens under such section." As Babin has said since this weekend, his bill would fully halt any new refugees arriving from Iraq and Syria — a position he is ready to defend against anyone.

“What they’re going to bring up over the holiday season is, ‘Mary and Joseph were refugees. Mary and Joseph when they went into Egypt were refugees,’” Breitbart News's Steve Bannon told Babin in an interview Wednesday.

“Well, Steve, I would just say this,” said Babin. “Mary and Jesus didn’t have suicide bomb vests strapped on them, and these folks do. You can see it in technicolor in Paris.”

As of right now, none of the eight identified suspects in the Paris attacks were refugees from Iraq or Syria. A passport found on one suspect, which matched one that was used by a refugee, was quickly determined to be fraudulent.
