In Watergate, we subpoenaed tapes for trial on April 16, got rulings from trial court, Appeals Court and and Supreme Court ruled for us on July 24. Took just over 3 months. Just over 2 weeks later, on Aug 9, Nixon resigned.
On March 1 we gave road map to Judge Sirica. He heard arguments ruled in our favor, defendants appealed, arguments were heard on and Appeals Ct ruled in our favor same day. On March 26 the full evidence went to the House Judiciary Committee. All it took was 25 days!
It doesn't take long to get results. Congress should:
1. ask Chief Judge Beryl Howell for the grand jury testimony Barr/Trump are hiding
2. hold Barr, Mnuchin, etc in contempt
3. Subpoena McGahn, Donaldson, Lewindowski, Mueller & anyone else they want & enforce them.
