Flynn to plead Fifth

Fresh from the wire, via Reuters:

Former White House National Security Adviser Michael Flynn will decline to comply with a subpoena from the Senate Intelligence Committee investigating possible Russian interference in the 2016 U.S. election, according to media reports on Monday.

Flynn will invoke his Fifth Amendment protection against self-incrimination, the Associated Press, Wall Street Journal and Fox News reported, citing sources close to Flynn.

I wonder if Trump has any thoughts on people who plead the Fifth?
