President Donald Trump’s decision to tap another interim US attorney in Washington tests the bounds of a federal statute governing temporary officials and reflects a growing trend of presidents leaning on temporary appointments for top roles.

Jeanine Pirro, co-host of the Fox News show “The Five,” will leave the network immediately after being appointed as interim U.S. attorney for Washington, D.C. A representative for Fox News confirmed her departure after Trump announced Thursday on Truth Social he has named Pirro for the position currently held on an interim basis by Ed Martin.
