WASHINGTON (Reuters) – California Democratic U.S. Representative Adam Schiff, who led the impeachment case against former President Donald Trump and was a member of the congressional panel that probed the 2021 Capitol attacks, announced a campaign for the U.S. Senate to represent the state. “Our democracy is under assault from MAGA extremists, who care only about gaining power and keeping it,” Schiff said in a statement on Thursday. “I look forward to campaigning hard in this race,” he added.
