Waxman accepted a position as a Professor of Law at
Columbia Law School in 2007. Waxman currently serves as the Liviu Librescu Professor of Law and faculty chair of the Roger Hertog Program on Law and National Security. On August 28, 2010, Waxman was quoted by
Charlie Savage on the front page of the
New York Times criticizing the
Barack Obama Presidency for choosing to prosecute Canadian
Omar Khadr who was only 15 years old when he was captured. In early 2012, as the Obama administration prepared to try
Khalid Sheikh Mohammed at
Guantanamo Bay detention camp, Waxman said on
NPR it would "be a big year for
military commissions. ... [T]he Obama administration [is] taking ownership of military commissions .... They are basically saying: We've corrected the problems of the Bush administration, and we're now going to use this as a tool in
combating terrorism .... There are a lot of doubters out there who see military justice and the military commission system as tainted or illegitimate .... The Obama administration wants to turn around that perception." In 2020, Waxman, along with over 130 other former Republican national security officials, signed a statement that asserted that
President Trump was unfit to serve another term, and "To that end, we are firmly convinced that it is in the best interest of our nation that Vice President Joe Biden be elected as the next President of the United States, and we will vote for him." ==Personal==
