President Trump’s nominee to be the number three official at the Justice Department has been involved in some of the highest-profile legal battles of the last few years, including a victory against the Obama administration when it tried to load up the National Labor Relations Board without consent from the Senate.

Noel J. Francisco is Trump’s pick to be the next solicitor general, and will go before the Senate Judiciary Committee on Wednesday.

Francisco first joined the federal government in 2001 when he became an associate counsel to President George W. Bush. Within two years, he became the Deputy Assistant Attorney General. In 2005, he moved to the private sector to work at Jones Day, the largest law firm in the United States and one of the 10 largest firms in the world.

While at Jones Day, he appeared before the Supreme Court several times.
