BOSTON (AP) — Jurors in the trial of former Massachusetts Treasurer Tim Cahill are set to begin their sixth day of deliberations in the public corruption case.

The jury has deliberated about 31 hours since Dec. 4 without reaching a verdict. Deliberations are set to resume Tuesday morning.

Cahill and his former campaign manager, Scott Campbell, are charged with violating state ethics laws by scheming to use $1.5 million in state lottery advertisements to boost Cahill’s 2010 independent campaign for governor.

Cahill testified that the ads were not for his campaign, but instead designed to defend the lottery against Republican attack ads.
