Prosecutors said the Democratic lawmaker paid a bribe to a state senator in exchange for support of a gambling bill that would have benefited one of Arroyo's clients.

Arroyo allegedly offered to pay $2,500 per month to the senator in return for the senator's support of sweepstakes-related legislation.
Prosecutors said Arroyo provided the senator with a check as an initial payment, with the expectation that additional payments would be made for the next six to 12 months. The senator was wearing a wire for the FBI during the transaction.
In October 2020, James Weiss, husband to former state Rep. Toni Berrios and son-in-law of one-time Cook County Democratic boss Joseph Berrios, was charged with his role in the scheme.
Weiss allegedly paid bribes to Arroyo beginning in November 2018 in exchange for Arroyo's promotion of legislation that would benefit Weiss. Weiss also allegedly conspired with Arroyo in the sweepstakes legislation bribery plot.
