Pretty easy question to answer from here
Is it illigal for both Joe Biden and Donald trump to defy a congressional subpoena?
If the answer is yes, then the articles of impeachment are valid and Donald trump is guilty of contempt of Congress, for ordering his cabinet to defy congressional subpoenas
If the answer is no, then you do not believe in equal treatment under the law
Joe Biden can be guilty of obstruction of congress but the president can’t because it’s a “partisan sham” and “exactly what Joe Biden did”
Trump supporters: subpoena the whistleblower! Subpoena the Bidens! Subpoena every one of the democrats so they can testify to THEIR crimes!
The whistleblower: lol nah I’m not gonna come if subpoenaed
The Bidens: lol nah I’m not gonna come if subpoenaed
Trump supporters: BUT THAT’S ILLEGAL!!!
And yes the Supreme Court has already ruled on this
Nobody, not even the president of the United States, can legally defy a subpoena
