A liberal member of Congress on Wednesday dubbed the most recent complaints about ACORN as "more blah, blah, blah."

Rep. Keith Ellison (D-Minn.) took aim at comments made last week by Rep. Mark Kirk (R-Ill.) suggesting that the Census Bureau should sever ties with the Service Employees International Union (SEIU) because it is too close with ACORN.

The Congressional Progressive Caucus member tweeted:

More blah, blah, blah re ACORN. Member drills rep of SEIU re association w/ ACORN. Are you now or have you evern been associated w/ ACORN?

The Senate previously voted to cut off federal funding for ACORN (Association of Community Organizations for Reform Now) after several staff members were caught on video giving tax advice to two individuals posing as a pimp and prostitute.

The SEIU previously backed one of Kirk's main Senate opponents Alexi Giannoulis (D).

Ellison also fired back at conservative attacks of the Community Reinvestment Act (CRA), which is designed to open credit to individuals in low and middle income communities. Some on the right have blamed it for playing a role in last year's mortgage in credit crisis.

The House Financial Service Committee member rebuked comments by a Heritage Foundation fellow speaking at a hearing before the panel on Wednesday.

He tweeted today:

More blah, blah, blah re CRA. Heritage Foundation speaker, David C. John, denies CRA role in financial crisis. What's wrong w/ these guys?

Mr. John: NO CFPA [the proposed Consumer Financial Protection Agency], but coordinating council for existing agencies. Same ones who failed consumer over last 8 years. Sorry, no good.
