ACORN, the embattled community organizing group, is a trending topic on Twitter a day after the Senate voted to cut off its federal funding.

The organization has come under fire since some of its members were accused of committing voter registration fraud during the 2008 election. Two conservative activists posing as a pimp and prostitute also caught ACORN employees on tape advising them on how to purchase a home and legally record income for tax purposes.

Trending topics are the top 10 most popular conversation subjects on Twitter. ACORN, which stands for Association of Community Organizations for Reform Now, is the seventh-most popular topic.

Some members of Congress have contributed to the buzz surrounding ACORN on Twitter. Sen. John Cornyn (R-Tex.) tweeted praise for the Senate vote. Rep. Roy Blunt (R-Mo.) took to Twitter to say that he will co-sponsor legislation in the House to de-fund ACORN.

Last Friday, the Census Bureau cut ties with ACORN in the wake of voter registration fraud allegations against employees at its Miami office.
