(CNN) - House Speaker Nancy Pelosi used her introduction of President Barack Obama at a Democratic fundraiser Saturday evening to once again blast third-party groups that are spending heavily on Republican campaigns this election cycle.
"Everything was going great and all of a sudden secret money from God knows where - because they won't disclose it - is pouring in,” Pelosi told a crowd of about 100 people gathered for a Democratic Congressional Campaign Committee (DCCC) fundraiser at the historic Van Dusen Mansion in Minneapolis, Minnesota.
Democrats have sought to make shadowy spending by outside groups a major campaign issue, blaming special interest organizations for heavily influencing congressional races without having to divulge their donor lists. Many of these groups, such as the conservative Crossroads GPS, are not required to disclose their donors because they are registered as nonprofit organizations.
In his remarks, Obama also blasted the massive spending by outside groups, saying Republicans are “being driven by the special interests who have been paying for their campaigns over the course of the last several months.”
Groups such as Crossroads GPS have invested heavily in several key races in the GOP’s effort to regain control of Congress this November. Republicans need to pick up 39 seats in order to win back the majority in the House.
Pelosi nonetheless has repeatedly said she remains optimistic, insisting in her remarks Saturday that Democrats “fully intend" to retain control of the House.
Democrats said they expected to raise $600,000 from the event. For $50,000 per couple, VIP guests were treated to a reception, dinner and a presidential photo line.
