Denver International Airport CEO Phil Washington on Monday blamed “unfounded partisan attacks” and obstruction tactics for sinking his nomination to lead the Federal Aviation Administration. He withdrew his name from consideration for FAA administrator late last week, in a development that became public Saturday night. For Washington, who was first nominated by President Joe Biden more than eight months ago, it was a frustrating end to a drawn-out process that included a combative confirmation hearing earlier this month. “It’s hard not to take it personally when people are making false accusations and taking cheap shots,” he said in an interview with The Denver Post.
