The FBI agent who investigated the Trump-Russia collusion claim sent a “jaw-dropping” text message suggesting that there was nothing to it, according to a Wisconsin senator who chairs the Homeland Security Committee. Peter Strzok, formerly the deputy assistant director of the FBI’s counterintelligence division, sent a text to his mistress, FBI attorney Lisa Page, on May 19, 2017 – just two days after the special counsel was appointed to investigate claims of President Donald Trump’s collusion with Russia during the 2016 campaign.
