It was a busy long weekend for President Donald Trump. From his Mar-a-Lago Club, 36 miles from the school where a deadly shooting claimed 17 lives last week, Trump spent more time than usual weighing in on the Russia investigation via Twitter. Trump fired off more than a dozen tweets about Russia following the latest charges in the investigation into Russian election meddling. He alternated between declaring his innocence, blaming former President Barack Obama for Russia's election interference, accusing Hillary Clinton of collusion, and suggesting the FBI could have prevented last week's Florida school shooting if it hadn't been so focused on the Russia investigation.
