Sen. Richard Blumenthal, D-Conn., said Donald Trump Jr. should be jailed if he does not comply with a subpoena to appear in front of the Senate Intelligence Committee, The Hill is reporting.

"The subpoena should be enforced," he said. "If he refuses to obey it, he should be locked up. There are no [executive] privileges for Donald Trump Jr. The son of the president doesn't have any of those privileges."

Blumenthal maintained Trump Jr.'s testimony to the Judiciary Committee in September 2017 appears to conflict with some findings in the report by special counsel Robert Mueller.

"There are a number of responses he gave that are challengeable based on the truth," said Blumenthal, who sits on the Judiciary Committee. "There are a number of areas that need to be scrutinized by the Intelligence Committee. His responses in the Judiciary Committee are certainly one of those areas."

The intelligence panel wants Trump Jr. to answer questions about his contact with Russia.
