Carol Costello

On October 16, 2018 it was announced by HLN that Costello was to be laid off, along with Michaela Pereira and Ashleigh Banfield, as part of the network's decision to scale back their live news programming. The final broadcasts for all three presenters took place on Friday, October 26, 2018.

On January 30, 2017, Costello announced that she would return to HLN to host a new program from Los Angeles.

In April 2015, Costello wrote that she became a "lapsed Catholic" after losing her younger brother Jimmy to cancer when she was 25. However, she stated that Pope Francis "reawakened my faith".

As a reporter and anchor, Costello has interviewed Jimmy Carter, Bill Clinton, Hillary Clinton and George H. W. Bush. Previously, Costello anchored the CNN early morning program CNN Daybreak and also was news reader and correspondent on American Morning. She was the anchor of CNN Daybreak, then a New York-based correspondent, and subsequently a contributor to The Situation Room. Costello hosted the 9 am–11 am slot of CNN Newsroom, based out of CNN's New York news bureau.

She previously worked out of the network's New York City bureau. She was part of CNN's Peabody-winning coverage of Hurricane Katrina and the 2008 presidential election, and also covered the Virginia Tech massacre, the inauguration of Barack Obama and the Casey Anthony trial. Costello has done in-depth reporting on bullying, coal ash, and women's issues. After a CNN viewer nominated her, Costello ran with the Olympic torch through the streets of Atlanta prior to the Atlanta Olympics.

A former resident of Atlanta, Georgia, Costello moved to the New York area after marrying Timothy Law Snyder in 2004. She and Snyder later moved to Baltimore, Maryland. In October 2015, Snyder was named president of Loyola Marymount University in Los Angeles. In January 2017, Costello cited her husband's relocation as a primary factor in her decision to leave CNN for HLN and move to Los Angeles.

Costello is a graduate of Minerva High School, a public high school in Minerva, Ohio, and Kent State University where she earned a B.A. in journalism. After attending Kent State University, Costello worked at Akron, Ohio's WAKR-TV as an award-winning police and court reporter. Following that Costello was an Emmy-award-winning anchor/reporter for WSYX, the ABC affiliate, and WBNS 10-TV, the CBS affiliate in Columbus, Ohio. She also worked as the 6 and 11pm news anchor for WBAL-TV in Baltimore between 1992 and 1995.
