Excuse me, I'm curious to know who has been appointed as the new CEO of WMATA? Could you please provide me with some details about their background and experience in the industry? I'm eager to learn about the strategies and visions they have for the organization and how they plan to tackle the ongoing challenges and improve the overall functioning of the transit system. Additionally, I'm also interested in knowing about the process that led to their selection and if there were any other candidates who were considered for the position.
