Steve Bannon, former chairman of President Donald Trump's 2016 campaign and White House chief strategist, was arrested on fraud charges related to an online fundraising scheme to build a U.S.-Mexico border wall.
Bannon, along with three others involved in the "We Build the Wall" GoFundMe campaign, were indicted by federal prosecutors in Manhattan who allege they defrauded hundreds of thousands of donors by using some of the more than $25 million raised for personal spending purposes.
Like many other Trump advisers, Bannon was fired by the president, just seven months after he took office in August 2017.
Bannon will be presented in court later on Thursday.
President Trump was asked what Bannon's arrest and those of other associates say about his judgment during a pool spray with the American and Iraqi press on Thursday.
"I have no idea," Trump said. "There was great lawlessness in the Obama administration. They spied on our campaign ... I don't think there should be a privately financed wall."
Here are six other Trump associates who have been charged with crimes since 2016: Paul Manafort, Rick Gates, Roger Stone, Michael Flynn, Michael Cohen and George Papadopoulos.
Manafort, Gates, Stone, Cohen and Papadopoulos have all been found guilty; Flynn's sentencing has been delayed and the Justice Department has moved to drop all criminal charges, prompting the lead prosecutor to withdraw.
