The House committee investigating the Jan. 6 attack on the Capitol on Tuesday subpoenaed Rudolph W. Giuliani and the legal team that pursued a set of conspiracy-filled lawsuits on behalf of former President Donald J. Trump that made claims of fraud in the 2020 presidential election.
In addition to Mr. Giuliani, Mr. Trump’s personal lawyer and a ringleader of the group, the panel subpoenaed three others: Jenna Ellis, who drafted a memo on how Mr. Trump could overturn the election by exploiting an obscure law; Sidney Powell, a lawyer whose organization raised millions of dollars based on false claims that election machines were rigged; and Boris Epshteyn, who pursued allegations of election fraud in Nevada and Arizona and participated in a call with Mr. Trump on the morning of Jan. 6, “during which options were discussed to delay the certification of election results,” the committee said.
