"Among the changes the legislation looks to tackle, it would limit the president’s pardon power, extend the deadline to prosecute former president and vice presidents for federal crimes that occurred before or during their time in the White House, enforce the Constitutional ban on a president enriching themselves, strengthen congressional subpoena power and reassert Congress’ power of the purse.
It would also mandate disclosing any contacts between the president and the Department of Justice, strengthen protection for inspectors general and federal whistleblowers, ensure the Senate’s role in confirming executive branch officials, strengthen enforcement of the rarely used Hatch Act, ensure transition resources after a presidential election and, in what appear to be direct swipes at Trump, require transparency of tax records for presidential candidates, and clarify the federal prohibition on foreign insistence to presidential campaigns."
About half of this is blatantly unconstitutional, and the other half is just "ORANGE MAN HURT US! WAAAAAAAAAAAAAH"
