As the newest cooperator with Special Counsel Robert Mueller, Rick Gates may become a powerful weapon against former Donald Trump campaign chairman Paul Manafort. Gates, who pleaded guilty Friday in Washington, was Manafort’s right-hand man and worked for a decade in his political consulting firm in Ukraine before joining the campaign. In a victory for Mueller and his probe of possible collusion by the campaign with Russia, Gates admitted he conspired with Manafort to defraud the U.S. by failing to disclose their work as unregistered foreign agents in Ukraine, and by hiding offshore bank accounts.

Symantec, MetLife, and others offering benefits to NRA members have dropped their association with the lobbying group following the Parkland massacre.

He needs to move fast to silence the doubters and coax Walmart’s legions of in-store shoppers to buy online as well.

Citi is refunding $335 million to U.S. customers whose annual percentage rate should have been lower. It plans to have checks in the mail by the second half of the year for 1.75 million affected accounts. The issue is a setback for CEO Mike Corbat, who has tied some of the bank’s future growth to expanding its credit-card operation.

China’s government seized temporary control of Anbang, and will prosecute founder Wu Xiaohui for alleged fraud. The move cements the downfall of a politically connected dealmaker whose aggressive global expansion came to symbolize the financial overreach of China’s debt-laden conglomerates.
