Special counsel Robert Mueller is now investigating whether President Trump attempted to obstruct justice into the federal probe of Russian interference in the presidential election last year.

While the FBI had originally said Trump was not being investigated for possible collusion between his campaign associates and Russia, the commander in chief is now under scrutiny for his actions in response to the probe, according to a Washington Post report. The news broke in the early evening on Wednesday, which also happens to be Trump’s 71st birthday.
