The terms of the offer gave Biden the authority to forgive up to 50 percent of the loan. "We have taken the step that was outlined in the law to cancel those loans, provide that economic assistance to Ukraine, and now Congress is welcome to take it up if they wish," Miller told reporters.Miller said Biden's statement of intent was delivered to Congress within the last week. While Congress does have the option to overturn the president's request, Miller said he expected U.S. lawmakers to support the debt cancellation. "I would be surprised if Congress took that step (to overturn the request) given the overwhelming bipartisan support in Congress for providing assistance, but we will follow the law," he said.With only two months until President-elect Donald Trump takes office, the Biden administration has pledged to shore up support for Kyiv before the presidential transition.
