Critics of New Jersey Gov. Chris Christie are becoming more vocal — and visible.
Opponents are showing up at his public and private events to hurl criticisms and question his knowledge of the Bridge-gate plot to tie up traffic at the world's busiest bridge.
The Republican governor says he didn't know about the plot, which was orchestrated by his aides.
A Christie fundraiser last week in Michigan drew 40 protesters, including one holding a sign that said, "Don't Mess with Our Bridge."
Other demonstrators have disrupted recent town halls. On Thursday, 10 people seated together spelled out "Bridgegate" with letters hand-painted on their T-shirts.
The possible 2016 presidential candidate says a public worker union is behind the protests.
But the union's political director says Christie should stop blaming others and answer constituents' questions.
