Federal grand jury probing Trump PAC's formation, fundraising efforts: Sources

A federal grand jury investigating the activities leading up the Jan. 6 attack on the U.S. Capitol and the push by former President Donald Trump and his allies to overturn the result of the 2020 election has expanded its probe to include seeking information about Trump's leadership PAC, Save America, sources with direct knowledge tell ABC News.

The interest in the fundraising arm came to light as part of grand jury subpoenas seeking documents, records and testimony from potential witnesses, the sources said.

The subpoenas, sent to several individuals in recent weeks, are specifically seeking to understand the timeline of Save America's formation, the organization's fundraising activities, and how money is both received and spent by the Trump-aligned PAC.

Neither a spokesperson for Trump nor an official with the Justice Department immediately responded to ABC News' request for comment.

Trump and his allies have consistently pushed supporters to donate to the PAC, often using false claims about the 2020 election and soliciting donations to rebuke the multiple investigations into the former president, his business dealings, and his actions on Jan. 6.

After the FBI raided Trump's Mar-a-Lago estate last month, Save America PAC sent out a fundraising email in which Trump urged supporters to "rush in a donation IMMEDIATELY to publicly stand with me against this NEVERENDING WITCH HUNT."

According to Save America's statement of organization filed to the Federal Election Commission (FEC), the committee was established just days after the 2020 election. At the time, the filing said the new committee is affiliated with the Trump campaign and the Trump Make America Great Committee, a small-dollar focused, joint-fundraising committee between the president's campaign and the Republican National Committee, which has been sending out donor solicitation emails for Save America.

Similar to regular political action committees, leadership PACs can only accept up to $5,000 per donor, far less than the upwards of $800,000 donations that the Trump campaign and the Republican Party's high-dollar joint fundraising committee, Trump Victory, had previously raised.

Since its inception, Save America PAC has brought in more than $135 million, including transfers from affiliated committees, according to disclosure records. As of the end of July, the PAC reported having just under $100 million in cash on hand.
