Ontario NDP staffer says sorry for offensive tweet

It was a tweet, heard across the country.

NDP leader Andrea Horwath sent out a tweet that read "Ford chaos in Ontario notwithstanding, my heart is in Humboldt, with so many other Canadians from across our country."

The tweet was quickly removed after getting backlash on social media.

Horvath admits it was obviously upsetting for some people.

But was it her?

She says it was a staffer who sent out the tweet, and once the staff person recognized it was a problem, apologized and took it down.

This after it was posted three times, twice with Humboldt spelled wrong.
