Donald Trump's administration is being sued over the alleged intimidation of civil servants by a group of senior lawyers who helped the Obama administration develop and adhere to a code of ethics.

United to Protect Democracy, named after a line from Barack Obama's farewell address, is taking the Department of Energy and the Department of Health and Human Services to court for records concerning the allegations, NPR reports .

Ben Berwick, one of the group's lawyers, wrote in a blog that the non-profit's goal is "protecting the civil service from purges, intimidation or politicisation."

The action comes after the group filed Freedom of Information Act requests for the documents.
