“Federal prosecutors in New York have subpoenaed the brother of one of the recently indicted associates of Rudy Giuliani, as they escalate their investigation in the campaign-finance case,” CNN reports.

“The subpoena to Steven Fruman is the latest indication of prosecutors’ actions since the rushed arrest two weeks ago of his brother, Igor Fruman, and another defendant, Lev Parnas, at a Washington-area airport. Since then, investigators have doled out multiple subpoenas and conducted several property searches, in one case blowing the door off a safe to access the contents.”

“Federal prosecutors told a judge this week that they are sifting through data from more than 50 bank accounts.”
