President Trump's campaign on Wednesday began assembling an all-star legal team to file challenges to election regularities in several battleground states, starting with a Court of Claims lawsuit in Michigan. Among the lawyers the president is activating include his private attorney Jay Sekulow, who will help campaign lawyers with matters before the Supreme Court as well as former New York City Mayor Rudy Giuliani and former Florida Attorney General Pam Bondi, officials said. Sidney Powell, the lawyer for former National Security Adviser Michael Flynn, may also be called upon, officials said.
