Four defendants of the non-profit organization We Build The Wall, including former Trump advisor Steve Bannon and its founder Brian Kolfage, are arrested on charges of conspiring to commit wire fraud and money laundering. The charges were stated in an indictment announced by the Acting U.S. Attorney for the Southern District of New York, which alleges that the four defendants defrauded the organization's donors, using the funds intended for the construction of the wall along the Mexico–U.S. border for personal expenses instead.
