NEW HAVEN (AP) - A Connecticut House speaker whose campaign was dogged by a campaign finance scandal has lost his bid for Congress.

Speaker Chris Donovan was the Democratic Party's endorsed candidate in the 5th District primary, but a federal investigation produced charges against his former campaign finance director and campaign manager. Former state Rep. Elizabeth Esty won the race.

Donovan's aides were arrested for allegedly participating in a scheme to hide the source of $27,500 in campaign contributions. Authorities said the donations were tied to an effort to defeat legislation that would have raised taxes on "roll-your-own" smoke shop owners.

Donovan has denied any knowledge of the alleged conspiracy and hasn't been charged.

Esty led in fundraising. She was endorsed by Emily's List, a group that backs Democratic women who support abortion rights.
