Abrams' spokesman Seth Bringman said Thursday she won't speak at the University of California-Berkeley's Goldman School of Public Policy commencement on May 20 because "she is proud to be in solidarity with the workers" of a local union of research and technical workers.

The decision, first reported by Politico California, comes as the Democrat is weighing her next political step. She's set to decide by next week whether to challenge U.S. Sen. David Perdue in 2020, and is also considering a run for president or a rematch against Gov. Brian Kemp.
