New York (CNN)The Manhattan district attorney's office has subpoenaed financial records related to Steve Bannon's crowd-funding border-wall effort, signaling that its criminal investigation into former President Donald Trump's chief strategist is advancing, according to people familiar with the matter.Prosecutors sent the subpoenas after Trump pardoned Bannon in late January for federal conspiracy crimes tied to the southern border-wall project, making Bannon among the Trump world figures -- including the former president -- subjects of criminal investigations by Manhattan district attorney Cyrus Vance.
