Transportation Department workers with 'exceptional' reviews told they're fired for 'performance' issues

President Donald Trump’s administration has started the mass firing of workers who are new to the civil service or have recently switched jobs.

Letters went out to dozens of probationary employees in at least one section of the Department of Transportation that said part of the reason they were being fired was for poor performance, according to a copy of the letter obtained by NBC News.

But most of those employees were rated as being “exceptional” performers by their supervisors.
