The special counsel’s Russia investigation is not only a political witch hunt but “an attack on our country,” President Donald Trump complained Monday, exhibiting mounting concern about the yearlong probe after federal authorities raided the offices of his personal attorney. “We’ll see,” he said, when asked if he might fire counsel Robert Mueller. Trump let loose after federal agents pierced the protective bubble around him, seizing records from the offices of longtime Trump attorney Michael Cohen, on topics including a $130,000 payment made to a porn actress who says she had sex with Trump more than a decade ago. Cohen has been an ardent defender in Trump’s business, personal and political affairs for more than a decade, and the probe’s expansion into the president’s inner circle left him fuming. Trump unleashed his sharpest invective to date against the sweeping investigation, calling the Monday search “a disgrace.” “It’s an attack on our country in a true sense,” he said, flanked by the nation’s top military brass, who watched the scene stone-faced.
