HALIFAX - Kevin O'Leary -- who drummed up headlines last month when he targeted Ontario's Kathleen Wynne -- has launched an aggressive attack on another Liberal premier.

In an "open letter" to Nova Scotia's Stephen McNeil on Facebook Wednesday, O'Leary said the province's economy is being strangled by high taxes and policies that discourage natural gas and oil exploration.

The reality TV show host and Conservative leadership candidate said he spoke to many people about the poor economy when he was in Halifax last weekend for a debate.

He said Nova Scotia has some of Canada's highest tax rates and one of the lowest economic outputs, and said that is not a coincidence.

The Facebook post had been liked 2,600 times within eight hours.

A spokesman for McNeil said the premier would not be commenting at this time.
