Ask your House Clowns why they didn't follow protocol to get them to testify before they shut down their "overwhelming" investigation.
Spare answered that, right above... the Senate had a better shot to get them immediately.... Trump couldn't fight them as ferociously to deny them, because they are the same party, he needs them all, to save him, from himself.
Executive Privilege is the same regarding House subpoenas and Senate subpoenas. The WH can challenge both and go to the courts for a ruling.
Once again you are trying to put the job of the House on the Senate. Your House Clowns refused to follow protocol. That's on them, not Trump, not the Senate.
He never executed his executive privilege rights in the house. NOT ONCE.... He simply defied the subpoenas and the law on everything. Another impeachment article on those unlawful actions.
The Senate, can go directly to the Supreme court in the impeachment trial, skipping years of litigation and appeals.
Trump can not stall it.
He wanted to stall being impeached, it did not work. In the Senate, he wouldn't want to stall his verdict.
