His legal team, however, told ABC News that Bolton is not willing to appear voluntarily.
"I stand ready at all times to accept service of a subpoena on his behalf," Bolton's attorney Chuck Cooper told ABC News.
In addition to Bolton, the person said two White House lawyers, John Eisenberg and Michael Ellis, have also been called to testify. It was not immediately clear whether Bolton, Eisenberg and Ellis would comply with the request.
While sources have told ABC News that Bolton was not listening in on the president's July 25 phone call with Ukrainian President Volodymyr Zelenskiy, they say he could provide a fuller road map into Trump's personal attorney Rudy Giuliani's dealings with Ukraine.
Fiona Hill, who handled Russian and European Affairs for the National Security Council under Bolton before leaving the White House in early July, testified before impeachment investigators earlier this month for nearly 10 hours.
Hill told lawmakers she raised concerns inside the White House and NSC about the early recall of U.S. Ambassador to Ukraine Marie Yovanovitch, as well as the work of Giuliani on matters related to Ukraine, according to sources familiar with her testimony.
Behind closed doors, she told lawmakers that Bolton had once referred to Giuliani as a "hand grenade" who would "blow everybody up," according to sources familiar with her testimony, the details of which were first reported by the New York Times.
Bolton, Hill told investigators, told her to raise concerns about Giuliani and his dealings with Ukraine with John Eisenberg, a National Security Council lawyer, following meetings with Gordon Sondland, the U.S. ambassador to the European Union, who testified under subpoena earlier this month.
Sources familiar with his thinking told ABC News that Bolton is open to speaking with congressional investigators.
In the case of Eisenberg and Ellis, the White House has sought to block administration officials from cooperating, though some have testified under subpoena from Hill investigators.
The White House did not immediately respond to a request for comment.
