(NECN/AP) - Former Massachusetts Treasurer Tim Cahill is back on the stand for a second day as prosecutors question him about taxpayer-funded lottery ads they say Cahill ran to promote his faltering 2010 gubernatorial campaign.
Cahill spent over two hours on the witness stand Thursday, answering questions from his lawyer.
Under cross examination Friday, prosecutor Jim O'Brien pressed Cahill repeatedly about why he authorized ads for the state lottery as his 2010 independent gubernatorial campaign faltered.
Cahill said he approved the ads to defend the lottery against criticism in ads run by the Republican Governors Association.
Cahill said lottery executives were concerned that the attack ads could damage the lottery's image and hurt sales.
Prosecutors have said Cahill schemed to "reach into the pocket" of the lottery to help his struggling campaign.
