FBI fires Peter Strzok, agent who sent anti-Trump text messages in 2016. Strzok had helped lead the investigations into Russia’s interference in the 2016 presidential election and into Clinton’s use of a private email server while she was secretary of state. Last summer, he was removed from the Russia inquiry by special counsel Robert Mueller when the Justice Department discovered texts between Strzok and former FBI attorney Lisa Page disparaging then-candidate Donald Trump in 2016.
