Pretty confusing IMHO. Here is the text of Sidney's Tweet:
1h: "The En Banc D.C. Circuit has denied the writ of mandamus requested by @GenFlynn -- split as expected along lines evident from the tone and tenor of the judges at oral argument. The opinion and dissents are here. https://sidneypowell.com/the-michael-t-flynn-case
It is a disturbing blow to the #RuleOfLaw"
Thank you!
