Former Secretary of State Hillary Clinton revealed that the “gutsiest” thing she’d done was to stay in her marriage with President Bill Clinton.

The Clintons famously stayed together despite the former president’s infidelity, most notably with then-White House intern Monica Lewinsky. After lying under oath about the nature of their relationship, the House of Representatives impeached Clinton for perjury and obstruction of justice charges in 1998. However, he was acquitted in the Senate.
