Plenty of celebrities were outraged by President Donald Trump’s firing of former FBI Director James Comey. As the investigation deepens into possible ties between Trump’s presidential campaign and the Russian government, those opinionated stars (and Democratic politicians and some pundits) have bandied the term “obstruction of justice” around. The term also cropped up after Comey’s testimony to members of the U.S. Senate on Thursday.

Trump hasn’t been charged with obstruction of justice. However, several other public figures have. There are many different types of obstruction of justice that fall under various state and federal statutes, according to the Ohio State Bar Association, though the term usually involves any actions that impede an official investigation or otherwise thwart the justice system. Some are misdemeanors and some are felonies, depending on the particulars of the incident and where it occurs.

Obstruction of justice has played a big role in cases involving athletes’ use of performance-enhancing drugs. Barry Bonds was charged with obstruction of justice after giving rambling testimony related to performance-enhancing drug use. He was ultimately found not guilty in 2015 after a “years-long, multimillion-dollar” legal battle, according to the Los Angeles Times. 

Another famous baseball player, Roger Clemens, was charged with obstructing Congress after testifying about performance-enhancing drug use. He was also found not guilty in 2012, The New York Times reported.

5. Richard Nixon

The most buzzed-about case in relation to the Comey testimony has been that of former President Richard Nixon. According to ABC News, obstruction of justice was included in the three articles of impeachment brought against Nixon. Nixon resigned before he was impeached, and was later pardoned.

Former President Bill Clinton was impeached on grounds of obstruction of justice, but the U.S. Senate acquitted him.
