After Trump demanded of Comey that he publicly state that he, Trump, was not personally under investigation (ignoring everybody else in his administration and the whole Russia investigation), and after then firing Comey for requesting more budget and personnel to pursue the Russia investigation, and after Comey stated under oath in testimony before Congress that Donald Trump was a "person of interest" in the investigation of Russian interference in the 2016 election, now the Washington Post is reporting that Robert Mueller, Comey's replacement after being fired by Trump, is, in fact, actually investigating Donald Trump himself for obstruction of justice.
Impeachable offense, it is.
Interesting development it is.
