There really isn't anything to discuss. Anyone who refuses to comply with a Congressional subpoena

[Atticus]

MUST OF COURSE be held in contempt and arrested. If the treasonous quisling AG refuses to pursue charges, lock the SOB's in the Capitol basement and impeach Barr. This is getting down to the brass tracks and we dare not blink.

1. Did you think Eric Holder should have been arrested when he refused to comply?

3. I'm not paying to read your link, but I'm sure Trump appreciates your even-handed

"both sides do it" approach.

4. You don't have to pay, just unblock ads (and I'm pretty sure Trump doesn't read DU). n/t

2. Have the FBI or Federal Marshalls pick up and arrest the derilicts when they refuse to comply

To appropriate subpoenas when Congress does their jobs. Oversight and obtaining needed information from Cabinet Departments on policies are part of Congress's job. The same with other areas of Government.

5. The FBI and Marshall's service are units of the executive branch not Congress.

The House has its own enforcement arm, the sergeant at arms.
