NYT:

The Justice Department has issued about 40 subpoenas over the past week seeking information about the actions of former President Donald J. Trump and his associates related to the 2020 election and the Jan. 6, 2021, attack on the Capitol, according to people familiar with the situation.

Two top Trump advisers, Boris Epshteyn and Mike Roman, had their phones seized as evidence, those people said.

The department’s actions represent a substantial escalation of a slow-simmer investigation two months before the midterm elections, coinciding with a separate inquiry into Mr. Trump’s hoarding of sensitive documents at his residence in Florida, Mar-a-Lago.

Among those the department has contacted since Wednesday are people who are close to the former president and have played significant roles in his post-White House life….

The Justice Department also executed search warrants to seize electronic devices from people involved in the so-called fake electors effort in swing states, including Mr. Epshteyn, a longtime Trump adviser, and Mr. Roman, a campaign strategist, according to people familiar with the events. Federal agents made the seizures last week, the people said….

The subpoenas seek information in connection with the plan to submit slates of electors pledged to Mr. Trump from swing states that were won by Joseph R. Biden Jr. in the 2020 election. Mr. Trump and his allies promoted the idea that competing slates of electors would justify blocking or delaying certification of Mr. Biden’s Electoral College victory during a joint session of Congress on Jan. 6, 2021.

Some of the subpoenas also seek information into the activities of the Save America political action committee, the main political fund-raising conduit for Mr. Trump since he left office, a new line of inquiry.
