Eight years ago according to Steve Herman, referencing the Guardian coverage:
Two years ago, Juli Briskman made headlines when she gave the finger to Trump as she cycled alongside the president’s motorcade in Virginia. The marketing company she worked for swiftly fired her. (She sued them.)

She couldn’t have imagined it at the time but Briskman, 52, has just won a local election – and she credits the incident for motivating her to run for office.
A decade later and we can still cheer Juli Briskman for doing what we would all have done given chance.
