Perjury and lying to the federal government are both crimes that could land a person in some serious legal trouble. If convicted of either crime, a person could be looking at up to five years in prison. This means that if a person is found to have lied during a congressional hearing or investigation, or simply lied to an FBI or other federal agent, actual jail time could result. The difficulty that comes in prosecuting these crimes is the requirement that the statements be made knowingly or willingly. This allows those being accused of, or investigated for, perjury, to assert a lack of knowledge at the time of the statement that the statement was false. However, this may not be compelling enough to defeat or avoid a prosecution if co [United States Code, title 18,] section 1001has a long and distinguished history, and has been used against notable, convicted liars Rod Blagojevich, Scooter Libby, Bernard Madoff, Martha Stewart, and Jeffrey Skilling. Furthermore, some might recall that President Bill Clinton faced impeachment not because of the inappropriate relationship, but rather because he lied about the relationship.
