BOSTON (CBS) – The jury in the corruption trial of former Massachusetts Treasurer Tim Cahill has entered its fourth day of deliberations.

The Suffolk Superior Court jury has been deliberating since Tuesday afternoon.

Cahill is on trial for allegedly violating state ethics laws.

Prosecutors say he used a $1.5 million taxpayer-funded lottery ad campaign to try and promote his failing 2010 independent gubernatorial campaign.

Cahill and his former campaign manager, Scott Campbell, face up to five years in prison if convicted.
