WASHINGTON, May 12 (UPI) -- This week the continuing saga of the Democratic primaries means that presidential politics is likely to dominate the news agenda again. But there are some issues and events on the homeland and national security issue list that might make the inside pages.

Monday, Patrick Fitch, the director of the Department of Homeland Security's National Biodefense Analysis and Countermeasures Center at Fort Detrick, Md., will make his first public remarks at the Center for Strategic and International Studies.

The national biodefense center, which will open shortly, provides a Level 4 laboratory in which research on the most dangerous and contagious diseases can be carried out. The center is likely to be one of the most controversial components of the U.S. biodefense effort, given how secret many of its activities are likely to be.

Defensive research is legal under the international treaties that ban biological weapons, but secrecy can make it tough to reassure observers that research is really defensive.

Also Monday, Ambassador Greg Schulte, the U.S. permanent representative to the International Atomic Energy Agency in Vienna, Austria, will address the Woodrow Wilson Center.
