ST. PAUL  (AP) — A leading DFL lawmaker says he's increasingly concerned about the reliability of tax revenue from electronic gambling machines that's supposed to help pay for construction of a new Minnesota Vikings stadium.

The House Commerce Committee met Wednesday to review the rollout of electronic pull-tab games in bars and restaurants. Tax revenue from those games is supposed to fund the state's $348 million share of the $975 million Vikings stadium to be built in downtown Minneapolis, but that revenue fell short of projections by $18 million through the end of 2012.

Backers of the new games say they need time to get more popular and expand to other bars, but committee chairman Rep. Joe Atkins says lawmakers only have a few months to decide whether to retool the stadium legislation.
