Rob Johnson and Kate Sullivan

Kate Sullivan posted a farewell message of gratitude on her Facebook page Wednesday, one day after she was ousted as weekday news anchor at CBS-owned WBBM-Channel 2.

As first reported here, Sullivan was dropped after five years on the CBS 2 anchor desk alongside Rob Johnson. Replacing her at 5, 6 and 10 p.m., starting October 19, will be Irika Sargent, who’s been anchoring at CBS-owned WFOR-TV in Miami.

Johnson will anchor solo until Sargent arrives, according to CBS 2 sources.

“I am so grateful,” Sullivan wrote. “Thank you to everyone for your kind words, love, and support in the past 24 hours. I was suddenly let go from CBS 2 yesterday and now no longer work there. As I said to my boss when he told me the news, I have nothing but supreme gratitude for five beautiful, difficult, fascinating, and challenging years in Chicago. God works…in mysterious ways. Always. Be. Kind. #‎Onward #‎Trueworth #‎Faith”

In a memo to staff Tuesday, Jeff Kiernan, vice president and news director of CBS 2, wrote: “We have enjoyed having Kate as a member of our news team during the past five years. She is a talented and experienced broadcaster and we have no doubt that she will continue to shine, both personally and professionally, in all of her future endeavors. We wish her all the best.”

Sullivan, 39, a native of Lakeville, Massachusetts, and graduate of the University of Notre Dame, joined CBS 2 in 2010 from WCBS-TV in New York, where she anchored morning and noon newscasts. She previously worked at KATV-TV, the ABC affiliate in Little Rock, Arkansas, and WSBT-TV, the CBS affiliate in South Bend, Indiana.
