At the time, Laxalt defended Domenici's integrity on CNN, calling him an honorable man who was supporting "no fewer than eight children."
The website for Adam Laxalt's law firm said he is a former U.S. Navy officer and lawyer who served in Iraq. He also worked for then-Sen. John Warner, R-Va., and as a special assistant to an undersecretary of state, according to the website.
He has also written a number of conservative columns against policies like Obamacare and the lifting of the military's "don't ask, don't tell" policy for gays for publications like the National Review Online, American Spectator and the Las Vegas Review-Journal. And he serves on the board of Catholic Charities of Southern Nevada.
Domenici is the latest in a long line of politicians who were forced to reveal secret children, from one-time Democratic presidential candidate John Edwards to former Republican Gov. Arnold Schwarzenegger. Just last week, U.S. Rep. Steve Cohen of Tennessee acknowledged that he's the father of a 24-year-old woman after the two were seen communicating on Twitter during the State of the Union address.
