An environmentalist group is joining the presidential fray with $1 million in television ads opposing Mitt Romney, disclosures showed Tuesday.

The League of Conservation Voters has previously dabbled in a few Senate races with $15,000 buys, but that changed with a pair of $500,000 purchases in the presidential race, coming last week and Tuesday.

The group’s top donor is Laurie Michaels, a Texas psycholgist, at $125,000. But its other top donors come from the financial industry, a group that has generally supported Mr. Romney.

Michael Bills of Bluestrem Asset Management and Amos Hostetter, an investment manager, have given $100,000, while Lawrence Linden, a banker at Goldman Sachs, has given $50,000, records show.

On Friday the group filed papers to run television ads in Denver, where Mr. Romney and President Obama have concentrated much of their advertising.
