“If the president fails to appear for the interview it’s an indication that he has something to hide,” Sen. Richard Blumenthal (D-Conn.) said Tuesday.

“Using [President Trump’s] own words, if you have nothing to hide, if you are innocent, then you should answer questions, sit down and answer questions,” Sen.

Blumenthal also said if Trump refuses to interview with Mueller, he should be subpoenaed.

GOP Sen. John KennedyJohn Neely KennedyMORE (La.) questioned whether that’s possible.

“I don't know whether he can be subpoenaed or what. I mean, you have the right in America not to testify, all things being equal; it's called the Fifth Amendment,” Kennedy said.

The senators spoke after The New York Times reported that some Trump advisers are suggesting he not interview with Mueller.
