The F.B.I.’s seizure of Representative Scott Perry’s phone this week was at least the third major action in recent months taken in connection with an escalating federal investigation into efforts by several close allies of former President Donald J. Trump to overturn the 2020 election, according to two people familiar with the matter.

The inquiry, which was begun last year by the Justice Department’s inspector general’s office, has already ensnared Jeffrey Clark, a former department official whom Mr. Trump wanted to install atop the agency to help him press his baseless claims of election fraud, and John Eastman, an outside lawyer who advised Mr. Trump on brazen proposals to overturn the vote result.

In June, federal agents acting on search warrants from the inspector general’s office seized phones and other electronic devices from Mr. Clark and Mr. Eastman. That same tactic was used on Tuesday to seize the phone of Mr. Perry, a Republican of Pennsylvania.

While the inspector general’s office had initial jurisdiction in the probe because Mr. Clark was an employee of the department, there have been signs in recent days that the investigation is increasingly being run by prosecutors from the U.S. attorney’s office in Washington. One of those prosecutors, Thomas P. Windom, is in charge of a broad investigation of a plan by Mr. Trump and his allies to create fake slates of electors to the Electoral College in states that were actually won by Joseph R. Biden Jr.

It remains unclear exactly how — or even if — the inquiry into Mr. Perry, Mr. Clark and Mr. Eastman is entwined with the broader investigation. In that inquiry, prosecutors are seeking to determine whether a group of Mr. Trump’s lawyers and several of his allies in state legislatures and state Republican parties broke the law by creating pro-Trump slates of electors in states he did not win and later by using them to disrupt a joint session of Congress on Jan. 6, 2021, where the final results of the election were certified.

Mr. Clark, Mr. Eastman and Mr. Perry all played roles in the effort to keep Mr. Trump in office, according to extensive evidence gathered by the Senate Judiciary Committee and the House select committee that is looking into the events of Jan. 6. The men also each had direct dealings with Mr. Trump, meaning the inquiry could ultimately lead to the former president.

At a series of public hearings, the House committee showed, for instance, how Mr. Eastman, a constitutional scholar, was one of the chief architects of the fake elector plan, advising Mr. Trump on its viability and encouraging lawmakers in some key swing states to go along with it….

Mr. Perry was instrumental in pushing Mr. Trump to appoint Mr. Clark as his acting attorney general over the objections of several other top officials at the Justice Department. At one of its presentations, the House committee released text messages in which Mr. Perry repeatedly pressured Mark Meadows, then Mr. Trump’s chief of staff, to reach out to Mr. Clark.

The House committee issued a subpoena to Mr. Perry in May, but he declined to comply with it. Mr. Clark and Mr. Eastman were also subpoenaed by the committee and repeatedly invoked their Fifth Amendment rights against self-incrimination.

On Wednesday, after Mr. Perry received his phone back from investigators, prosecutors told him that he was a witness in, not a subject of, their inquiry, according to one of his lawyers, John Irving.
