Here's a quote from the video:
“When I ran project vote, the voter registration drive in Illinois, ACORN was smack dab in the middle of it. Once I was elected there wasn’t a campaign that ACORN worked on down in Springfield that I wasn’t right there with you. Since I have been in the United States Senate I’ve been always a partner with ACORN as well. I’ve been fighting with ACORN, along side ACORN, on issues you care about my entire career.” [emphasis is mine, RV]So, all through the 2008 campaign as well as last year's ACORN Prositute Scandal, Mr. Obama stated that he was barely connected with this organization.
