Virginia’s U.S. Senator Mark Warner joined fellow Democrats on the Senate Intelligence Committee signing a letter to President Obama today calling for the declassification and release to the public of further information on efforts by the Russians to interfere in the U.S presidential election last month.

Warner joined Ron Wyden, Jack Reed, Barbara Mikulski, Martin Heinrich, Angus King and Mazie Hirono signing the letter, which stated that further information would be forwarded to the president in a follow-on classified letter.
