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.
