Brett Shipp, a veteran investigative reporter at WFAA, resigned Tuesday to run for the United States Congress as a Democrat.

Shipp enters a crowded Democratic field of primary candidates running to unseat Republican Congressman Pete Sessions in Texas’ 32nd District.

For 22 years, Shipp has worked at WFAA, winning the top journalism awards in broadcasting. Those include three Peabody Awards, two duPont Silver Batons and a duPont Gold Baton. His father, Bert Shipp, worked at WFAA for 40 years as a reporter and assignments editor.

“We are grateful for the many contributions Brett has made to WFAA and the field of journalism,” said Executive News Director Carolyn Mungo.

Shipp has scheduled a Thursday news conference to announce his candidacy.

Shipp’s last day as an employee of WFAA was Tuesday.
