“Ms. Boothe notified the Speaker about the subpoena as she was required to do under House Rules. She fully intends to cooperate with the investigation," Elliot Berke, a lawyer at Berke Farah LLP, said in a statement.
Prosecutors with the Southern District of New York (SDNY) are seeking Boothe's testimony after Sessions was referred to as "Congressman-1" in an indictment that alleged that two Giuliani associates, who were recently charged with campaign finance violations, lobbied the GOP lawmaker to help them oust then-U.S. Ambassador to Ukraine Marie Yovanovitch from her post.
Sessions has not confirmed whether he is Congressman-1, but he says he has met multiple times with the two Giuliani associates, Lev Parnas and Igor Fruman. The two allegedly donated to Sessions amid efforts to remove Yovanovitch, but Sessions has denied that he took any official action as a result of meetings that he had with the two Florida businessmen.
Sessions in a statement this month said it was only after "several congressional colleagues reported to me that the current U.S. ambassador to Ukraine was disparaging President TrumpDonald TrumpGraham says he hopes that Trump runs again Trump says Stacey Abrams 'might be better than existing governor' Kemp Executive privilege fight poses hurdles for Trump MORE to others" that he wrote a letter to Secretary of State Mike PompeoMike PompeoRepublican lawmakers raise security, privacy concerns over Huawei cloud services WashPost fact-checker gives Pompeo four 'Pinocchios' for 'zombie' claim about Obama Iran deal Poll: Biden, Trump statistically tied in favorability MORE raising concerns about the diplomat.
“My entire motivation for sending the letter was that I believe that political appointees should not be disparaging the President, especially while serving overseas," he said at the time.
"I have been friends with Rudy Giuliani for more than 30 years,” he said, adding that he does not "know what his business or legal activities in Ukraine have been.”
A spokesman for SDNY did not return a request for comment.
Sessions is said to also be under subpoena to provide documents and other information to federal investigators, according to reports, as they seek to examine whether there was a scheme to funnel foreign money to U.S. politicians.
The subpoena also reportedly is seeking information about Giuliani and his two business associates, who had been helping Giuliani investigate Democratic presidential candidate and former Vice President Joe BidenJoe BidenHaiti prime minister warns inequality will cause migration to continue Pelosi: House must pass 3 major pieces of spending legislation this week Erdoğan says Turkey plans to buy another Russian defense system MORE before their arrest.
House Democrats are also examining the circumstances surrounding the Trump administration's contacts with Ukraine, particularly whether Trump and Giuliani withheld nearly $400 million in financial aid to Ukraine as leverage to get a commitment from Ukrainian President Volodymyr Zelensky to investigate Biden, one of his top 2020 political rivals, as well as interference in the 2016 election.
Multiple witnesses have testified behind closed doors in recent weeks, voicing disappointment and frustration about Yovanovitch's sudden removal.
Yovanovitch earlier this month also delivered damning testimony in a nearly 10-hour closed-door meeting before House investigators, accusing top Trump officials of staging "a concerted campaign” against her based on "unfounded and false claims by people with clearly questionable motives.”
“I do not know Mr. Giuliani’s motives for attacking me,” she said, according to her prepared remarks. “But individuals who have been named in the press as contacts of Mr. Giuliani may well have believed that their personal financial ambitions were stymied by our anti-corruption policy in Ukraine.”
