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.

Every person involved in this conspiracy must be investigated and prosecuted to the fullest extent of the law,' Tulsi Gabbard says.
