The introduction of a grand jury in the Trump-Russia investigation shows a push for criminal prosecution and could lead to the President's impeachment, according to expert Brian Klaas.
The investigation into claims that Russia meddled in last year's presidential election on behalf of Donald Trump has moved to a grand jury, which can issue subpoenas to force people to appear before the hearing and give testimony.
Klaas, a fellow in comparative politics at the London School of Economics, told Julia Hartley-Brewer: "What this signals is there’s a serious push for a criminal prosecution. We don’t know whether Trump himself will be a target of that."
He believes that this could be "a much more serious investigation than Trump is willing to accept" and if criminal allegations are made towards Trump "that would probably lead to impeachment."
Political change is starting to shift as "we’ve seen signs of his party turning on him so they’re basically ignoring his directives in Congress."
Klass added: "Given Trump's, shall we say, loose relationship with the truth he’s going to be exposed to a very huge risk if he ends up under oath.
"The odds that this will end with Trump being seen as this masterful president are basically none."
