Jill Biden's Denver trip disrupted by aircraft issue.
First Lady Jill Biden's flight to Michigan was forced to return to Denver due to an "aircraft issue," and her trip to the Great Lakes State has been postponed to a later date. Biden was in Colorado as part of a multi-state "Investing in America" blitz to promote President Biden's economic initiatives. She was scheduled to visit Delta College in Michigan to talk about the school's workplace training programs and highlight the importance of investing in career-connected learning and workforce training programs.
