JACKSON, MI -- Eighteen people showed support for presidential nominee Donald Trump at a "flash mob" Tuesday, Aug. 30, in the birthplace of the Republican Party.

The planned gathering looked bleak at its 4 p.m. start time, but Leoni Township Trustee Robert Sutherby showed up a half hour later with signs for the five people standing at the corner of N. West Avenue and W. Monroe Street.

People then began to exit their cars and grab signs.

A few people brought their own sign, ranging from "Veterans for Trump" to "Hillary for prison."

"The plan is grassroots, for a real person, not a politician," Sutherby said.

By the time the mob concluded at 5:30 p.m., almost 20 people stood at the intersection supporting Trump.

"I think this worked out," Sutherby said.

People driving by in cars greeted the supporters with honks of solidarity -- and obscenities and hand gestures of opposition.

The supporters main chant was, "Lock her up, throw away the key," in reference to Democratic presidential candidate Hillary Clinton.

The "flash mob" was part of a series of showings across the state Tuesday hosted by the Michigan Conservative Coalition.
