Barak Cohen was quoted in the CBC article, “Trump-Russia Grand Jury: What You Need to Know,” regarding what a grand jury is and its possible significance in Robert Mueller's investigation into possible collusion of President Donald Trump’s presidential campaign with Russian interference in the 2016 election.

"This is a signal that they've found something of interest," says former federal prosecutor Barak Cohen.

"That doesn't mean an indictment is likely, or that a crime probably happened," he says. "It just means that Mueller and his team have enough evidence now to believe they should cross the threshold."

"Once it formally becomes a grand jury investigation, it becomes a little more significant, a little more formal," Cohen says.

"It's a lot clearer if somebody's trying to interfere."
