Minnesota TV viewers will receive a special message from the Sopranos' Vincent Curatola, aka Johnny "Sack" Sacramoni, warning them that Al FrankenAlan (Al) Stuart FrankenOvernight Tech: Senate panel subpoenaed ex-Yahoo chief | Twitter gives all users 280 characters | FBI can't access Texas shooter's phone | EU wants tax answers from Apple Week ahead: DHS nominee heads before Senate | Ex-Yahoo chief to testify on hack | Senators dig into election security Feinstein: Sessions should re-testify on Russia meetings MORE supports the Employee Free Choice Act.

Curatola is appearing, for the second time, in an ad paid for by Coalition for a Democratic Workplace (CDW), a group founded to oppose the bill.

The Employee Free Choice Act, which Franken supports, would allow workers to form unions by obtaining signatures on a sign-up sheet. Currently, the National Labor Relations Board mandates secret ballot elections to certify the formation of unions.

CDW alleges this opens workers to pro-union intimidation; labor unions and supporters of the bill say the current system opens workers to anti-union intimidation from employers.

The ad begins airing statewide in Minnesota today. In it, Curatola appears as a bullying labor boss who doesn't like Sen. Norm Coleman (R-Minn.), whom Franken is challenging, because Coleman opposes the Employee Free Choice Act. See it below:
