The leaders of the U.S. Senate Intelligence Committee said on Tuesday they would subpoena two of former national security adviser Michael Flynn's businesses after Flynn declined to comply with a subpoena for documents in the panel's Russia probe.

"While we disagree with Gen. Flynn's lawyers' interpretation of taking the Fifth ... it's even more clear that a business does not have a right to take the Fifth," the panel's vice chairman, Democrat Mark Warner, told reporters, referring to Flynn's decision to invoke his Fifth Amendment right against self-incrimination.
