Independent national security journalist Marcy Wheeler detailed how the timing of the Southern District of New York's subpoena for a trove of information from Donald Trump's inaugural committee may signal a change in special counsel Robert Mueller's investigation.

On Monday evening, ABC News reported that the SDNY had subpoenaed the Trump inaugural committee, and subsequent reports revealed that the committee is accused of money laundering and making false statements.

"The subpoena seeks information relating to a bunch of conspiracy-related crimes," Wheeler noted, "parallel to the crimes Mueller looked at in the Russian investigation, but including other countries."

The inaugural committee subpoena may also help explain why Guy Petrillo, an alum of the Southern District, recently stopped representing Michael Cohen, the journalist added.

"Since Cohen refused to cooperate with SDNY on what would have been this investigation," she wrote, "he’s likely to face further criminal exposure for his efforts to get rich off the big party."

Wheeler went on to say that she suspects the SDNY "is only now getting around to digging into what is surely a vast swamp of corruption because Mueller asked them to wait" until the inauguration portion of his own investigation was done.

This subpoena, and a potential ending of the special counsel's investigation into the inauguration, may be in line with reports that Mueller will soon wrap up his probe, the national security expert added.

It also "may mean that after the results in Mueller’s Russian investigation soften Trump up," Wheeler concluded, "this investigation will just be ripening, possibly even at a time where Trump can be indicted."
