A Democrat who served at the U.S. agency that hears appeals by federal government employees when they are fired or disciplined has filed a lawsuit challenging Republican U.S. President Donald Trump's attempt to fire her.

Eight government watchdogs have sued over their mass firing that removed oversight of President Trump’s administration.

Eight inspectors general whom Donald Trump fired from their federal agency watchdog posts are suing for their jobs back, adding to the legal scrutiny over Trump’s first weeks of decisions in the White House and raising questions about his political intentions.

Congress was not given the legally required 30-day notices about the removal of the inspectors general – something that a top Republican decried.
