Laura Ingraham’s new show on Fox News, “The Ingraham Angle,” debuted at number one in the ratings in Monday night’s 10 p.m. slot.

Nielsen Media Research showed Ingraham with 3.274 million total viewers, while Lawrence O’Donnell’s show on MSNBC had 2.598 million, and Don Lemon’s CNN show had just 1.336 million.

In the 25- to 54-year-old demographic, the most coveted by advertisers, Ingraham had 622,000 viewers. O’Donnell had 612,000 viewers in that bracket, and Lemon had only 511,000.

To kick off her new show, Ingraham scored a rare interview with White House Chief of Staff John Kelly and also had as a guest former Attorney General Michael Mukasey.

Ingraham is the founder and editor-in-chief of LifeZette. She has been a regular Fox News contributor for more than a decade, appearing frequently on “The Sean Hannity Show” and “Fox & Friends.” She also hosts “The Laura Ingraham Show” on radio, where she’s the most listened-to female political talk-show host in the nation. Her new book, “Billionaire at the Barricades: The Populist Revolution from Reagan to Trump,” is now on The New York Times Best Sellers list.

Ingraham is a former white-collar defense attorney. She was born and raised in Connecticut, but has lived in the Washington, D.C., area for more than 20 years.

This week, “The Ingraham Angle” will also have as guests House Speaker Paul Ryan and Supreme Court Justice Clarence Thomas on Wednesday, November 1.
