The G-20 giveth and the G-20 taketh away.

Allegheny County Executive Dan Onorato announced his candidacy for governor this afternoon, citing the progress his region had made and the recognition it had earned from the recent G-20 summit.

But the high-profile economic meeting ricocheted against his candidacy as his announcement speech on the South Side was repeatedly interrupted by demonstrators protesting police tactics during the G-20 summit on Sept. 24-25. Police arrested about a half-dozen protesters and removed them from the IBEW hall, where Mr. Onorato was giving his speech.

A Pittsburgh police sergeant said it was likely the arrested protesters would be charged with trespassing and released.

Mr. Onorato spoke to hundreds of supporters, promising to provide the kind of leadership for the state of Pennsylvania that, he said, he had demonstrated for Allegheny County. He said his candidacy would highlight economic development, education, and efforts to improve the state's job climate.
