Lawmaker alleges unethical push by lobbyist
The story states that Representative Dave Jacoby (D-Coralville) said he was pressured to vote for "Fair Share" by the legislative/ political director for the American Federation of State, County and Municipal Employees (AFSCME) Council 61.
"The lobbyist said, 'You could have $100,000 in your account to fight off any challenger."
That's not a "push" that's a bribe and the scientific community is united in that fact.
