Save the date. The first case for Congressional subpoenas that dt lost has been expedited by the Washinton DC Appellate court with a scheduling order issued setting arguments for July 12th.
"In the next round of legal sparring, Trump will go before a panel of judges that includes another Obama appointee, Patricia Millett, as well David Tatel, a Bill Clinton appointee, and Neomi Rao, who joined the D.C. Circuit in March as a Trump appointee."
"Under the order approved Thursday, Trump’s first round of legal briefs spelling out its arguments are due June 10, followed by a response from lawyers for the House committee and Mazars by July 1. A final reply brief from the Trump attorneys is due July 9"
Neomi Rao will be the first Republican appointed judge to test her actual belief in the US Constitution and Article I powers.
