Federal authorities are investigating another potential ricin attack at Joint Base Anacostia-Bolling in Southeast Washington, Senate Majority Leader Harry Reid (D-Nev.) said Tuesday.

Asked about the release earlier Tuesday of the man accused of sending ricin-laced letters to President Obama and Sen. Roger Wicker (R-Miss.), Reid said there was another "alleged ricin incident" at Bolling on Tuesday.

He did not offer further details.
