HARTFORD, Conn. (AP) - The Connecticut Senate president says legislation authorizing fantasy sports is unlikely to pass after the Connecticut attorney general said it could jeopardize the state's slot machine revenue-sharing agreement with the two federally recognized Indian tribes.

Attorney General George Jepsen said in a letter released Monday there's a "high degree of uncertainty" as to whether daily fantasy sports are games of skill or games of chance. If the latter, Jepsen says they could violate the agreement if played on a device considered a video facsimile.

The Mashantucket Pequots and Mohegans have exclusive rights to operate video facsimile games in exchange for providing the state with 25 percent of the revenues.

Democratic Senate President Martin Looney says the bill is unlikely to pass given the "substantial risk" it presents to the agreement.
