'There's no question': Ex-advisor issues Canada warning about Trump's threats

President-elect Donald Trump has caused consternation in Canada with his threats to make the country part of the USA and his floating a 25% tariff on any imports. And a former economic adviser says it's part of his typical negotiation tactics.

Speaking to the Canadian Broadcast Corporation, Stephen Moore — an economic adviser to Trump during the first administration — said it's an effort to create leverage.

"I think there's no question that that's what he's doing here," Moore told CBC News in an interview.
