Subpoenas have been issued by a federal grand jury in an investigation into the political action committee known as Save America PAC. This organisation was established at the time when Donald J. Trump was making unsubstantiated claims about election fraud.

An important new development in the wide investigation into the roles that Donald J. Trump and his supporters played in attempting to change the results of the 2020 election is the revelation that federal prosecutors are collecting evidence regarding a political action committee called Save America PAC.

A federal grand jury in Washington is investigating the establishment of a fund-raising operation that Donald J. Trump established after he was unsuccessful in his bid for the presidency in the 2020 election. At the time, Trump was attempting to raise millions of dollars by falsely asserting that the results had been tainted by widespread voting fraud. The grand jury is looking into both the formation of the organisation and its spending.

The Justice Department is interested in the inner workings of Save America PAC, which was Mr. Trump’s primary fund-raising organisation after the election, according to subpoenas that were issued by the grand jury and the details of which were reported to The New York Times. On Wednesday, more subpoenas of a similar kind were sent to junior and midlevel employees who had previously worked for Mr. Trump’s presidential campaign or in the White House.

The fact that federal prosecutors are now seeking information about the fund-raising operation is a significant new turn in an already expansive criminal investigation into the roles that Mr. Trump and some of his allies played in trying to overturn the election. These efforts culminated in the mob attack on the Capitol on January 6, 2021. The fact that federal prosecutors are now seeking information about the fund-raising operation is a significant new turn in an already expansive criminal investigation.

The widened investigation that began on January 6 is ongoing at the same time that Mr. Trump is being investigated by the federal government on a completely different front. This investigation is centred on Mr. Trump’s decision to keep hundreds of government documents marked as classified after he left office, as well as his refusal to comply with efforts by the National Archives and the Justice Department to compel the return of those documents.

On Thursday, the Department of Justice made a request to a federal court, asking her to reconsider her order to temporarily prevent prosecutors from receiving access to secret materials for the purpose of using them in the investigation they are conducting.

The fresh subpoenas that were issued in connection with Mr. Trump’s fundraising operation did not make it apparent what potential criminal or crimes the Justice Department would be investigating. The House select committee that is investigating the attack on the Capitol and what led up to it has also been investigating Mr. Trump’s fund-raising operation. The committee has raised questions as to whether or not Mr. Trump’s campaign misled donors by appealing to them with misleading information about election fraud.

The investigation into Mr. Trump that was launched on January 6 by the Justice Department has so far focused mostly on a scheme to build slates of electors who had committed their support to him in seven crucial swing states that Joseph R. Biden Jr. had won.

Even while the two grand juries looked to be focusing on some of the same topics, it appeared that the fresh subpoenas were issued by a separate grand jury than the one that has been collecting information regarding the so-called fake electors plot.

It would seem that the investigation into Mr. Trump’s campaign fundraising is still in its infancy at this point.

Save America’s formal registration with the Federal Election Commission took place on November 9, 2020 — two days after news media projected that Joe Biden would defeat Donald Trump in the presidential election.

Since that time, it has served as an important node in an operation run by Mr. Trump’s team and has been the driving force behind the success of the Republican Party’s low-dollar fund-raising efforts.
