'Obamagate': Donald Trump calls for Barack Obama to testify and wants officials to be 'jailed for 50 years'
Donald Trump has called for Barack Obama to be hauled before Congress, and for his predecessor's officials to be "jailed for 50 years". The US president has defined as "Obamagate" an episode involving the "unmasking" of his first national security adviser Michael Flynn after his name appeared in redacted form in intelligence reports related to Russia. He claims that, during the presidential transition period at the end of 2016, the Obama administration abused its power for political reasons in targeting Mr Flynn. Mr Trump appeared set to make it an issue in the upcoming election campaign. He told Fox Business that senior Obama officials should "have been in jail a long time ago, and I'm talking with 50-year sentences. It is a disgrace what's happened. This is the greatest political scam, hoax in the history of our country." The president added: "People should be going to jail for this stuff and hopefully, a lot of people are going to have to pay." Mr Obama responded by tweeting: "Vote."
