U.S. Sen. Richard Burr will look into terrorism involving weapons of mass destruction.

The Winston-Salem Republican announced today that he and Sen. Bob Casey, a Pennsylvania Democrat, are starting the Senate Caucus on WMD Terrorism.

The bipartisan group of eight senators will highlight the problem of terrorist groups obtaining nuclear, biological and chemical weapons and discuss policy responses.

"We must ensure the U.S. government continues to make the prevention of, and preparedness for, bioterrorism and other WMD threats a top priority," Burr said in a statement.

The other members of the caucus are Democratic Sens. Evan Bayh and Russ Feingold; Republican Sens. James Inhofe, Saxby Chambliss and Johnny Isakson; and independent Sen. Joe Lieberman.

U.S. Sen. Richard Burr is going to Guantanamo Monday.

The Winston-Salem Republican will visit the Guantanamo Bay military base in Cuba that currently holds about 245 men on suspicion of terrorism.

He'll be joined on the day-long visit by David Vitter of Louisiana, Pat Roberts of Kansas and Sens. James Inhofe of Oklahoma, who is organizing the trip.

President Obama signed an executive order calling for the closure of the prison within a year.

Spokesman Chris Walker said Burr wants to understand the "facts on the ground" before making a final decision on his thoughts on Obama's order.

"So far, he's unconvinced that moving trained terrorists to the U.S. is in the best national security interests," he said.
