Out of Alabama's nine congressional members, only one has confirmed he has rejected his salary during the federal shutdown. That would be Republican Congressman Gary Palmer of District 6.
"Congressman Palmer has requested that his pay be withheld for the duration of the shutdown and will not be paid," stated an email response from Palmer's press secretary Elizabeth Hance. According to Hance, Palmer made the request more than a week ago. I checked multiple lists and did not see Palmer's name included. That does not mean he did not make the request.
I reached out via phone and email to all nine of Alabama's congressional members, and asked whether they intend to decline or donate their pay during this shutdown. The majority of their offices did not give an answer about their intentions at the time. But, said they will get back to me with a response.
At this time, more than 800-thousand federal workers are impacted by the present federal shutdown. They are either furloughed, or are called to work without pay. More than 80 congressional members, both Democrat and Republicans, declining their salaries say this is their way of standing in solidarity with workers forced to forego their paychecks.
