And it isn't just theoretical. In a recent Supreme Court case (US v. Rita) Victor Rita (not a close friend of the President or Vice President) was convicted of lying while giving grand jury testimony.
At sentencing, he argued that he should receive a sentence below the range in the federal guidelines because he was elderly and sick, had served for 24 years as a Marine, including tours in Vietnam and the first Gulf War, and was vulnerable to abuse in prison because he'd worked in criminal justice on behalf of the government.
After receiving a within-the-guidelines sentence of 33 months, Rita appealed on the ground that the sentence was unreasonable given the nature of his offense and his personal circumstances. The Bush administration opposed Rita's appeal.
Silly Victor Rita. How dare he assume that his service in the Marines would matter if he wasn't a close personal friend of the President and had lied under oath to protect our grotesque Vice President.
Worst President in the World.
