U.S. President Donald Trump accused former President Barack Obama of "treason" on Tuesday, accusing him, without providing evidence, of leading an effort to falsely tie him to Russia and undermine his 2016 presidential campaign.

Besides Obama, President Trump on Tuesday rattled off a list of people he accused of acting criminally "at the highest level."

Former President Barack Obama denied President Donald Trump's “bizarre allegations" that he was the Russiagate “ringleader," in a rare public statement Tuesday evening.

In terms of day-to-day events, the former president tends to steer clear of the arena. There are, however, occasional exceptions.

The statute of limitations likely limits the Trump administration's ability to prosecute Obama for his alleged actions during the 2016 election.

Former Obama administration officials named in new revelations surrounding the origins of the Trump-Russia investigation have been silent amid allegations they "manufactured" intelligence that led to the opening of the yearslong probe.
