President Trump has put his personal lawyer, Rudolph W. Giuliani, in charge of his campaign lawsuits related to the outcome of the election, as well as all public communications related to them, four people familiar with the move said on Friday. Mr. Trump turned to Mr. Giuliani earlier on Friday in reaction to the latest setback he faced in court, this one relating to votes in Maricopa County, Ariz., the people said.
