Monica Lewinsky began as a White House intern in 1995. President Bill Clinton began an affair with her that year — it continued for two years, and came to light nationally in 1998.

In Lewinsky's essay "#MeToo and Me" in "Vanity Fair's Women on Women," Lewinsky writes about how the #MeToo movement has shaped her understanding of the affair.

"I—we—owe a huge debt of gratitude to the #MeToo and Time's Up heroines. They are speaking volumes against the pernicious conspiracies of silence that have long protected powerful men when it comes to sexual assault, sexual harassment, and abuse of power," Lewinsky wrote.

"In 2014, in an essay for Vanity Fair, I wrote that following: 'Sure, my boss took advantage of me, but I will always remain firm on this point: it was a consensual relationship. Any 'abuse' came in the aftermath, when I was made a scapegoat in order to protect his powerful position.' I now see how problematic it was that the two of us even got to a place where there was a question of consent. Instead, the road that lead there was littered with inappropriate abuse of authority, station, and privilege," Lewinsky wrote.

Astronauts William Oefelein and Lisa Nowak worked together at NASA. They met while training in the space shuttle program in 1996, and had an affair from 2004 to 2006, according to TIME.

In 2007, Nowak drove from Houston to Orlando to confront Ofelein's new girlfriend, Air Force captain Colleen Shipman. Nowak brought various weapons — including a BB gun and a steel mallet — to her planned confrontation, and brought diapers with her on her road trip to elimate the need for pit stops, according to TIME.

Nowak attacked Shipman with pepper spray; Nowak was ultimately arrested by police, and through a plea deal was able to avoid jail time and instead serve one year of probation, according to TIME.
