They can’t refuse a hearing now can they?
one would hope not, but he’s not a republican
Yes, the chairman of the appropriate committee is responsible to schedule hearings, if he chooses not to, the minority has no recourse.
Although, if Enzi and Hatch are denied, they should do what the Dems did when they were in the minority, hold a (non-official) hearing somewhere in the Capitol, in a hotel ballroom if they have to, use a table to indicate the missing Dems with namecards, invite the media, we know Fox would show up at the very least, investigate the matter. They would not have the power of subpoena, but then they wouldn't have it if the Dem chairman allows a true hearing anyway.
But they should at least make the attempt to get the facts of the matter out into the public purview.
