Will counsel Mueller be subpoenaed to the Congress?

Adam Schiff, the House Intelligence Committee Chairman said on Sunday that Congress was "running out of time" to have former special counsel Robert Mueller testify, adding that he hopes a "final conclusion" is reached on his possible testimony "this week." 

"We have been in private discussions with the special counsel's office," Schiff told CNN's "State of the Union." "It is not clear that he will refuse to come in voluntarily; we are negotiating what the conditions of that appearance might be. But yes, we are running out of time." 

"I hope that we'll reach that decision this week because we want to have him come in during July and I think that's going to be the case ... whether it is voluntary or involuntary by subpoena," Schiff added.
