House Appropriations Committee Chairman David Obey's (D-Wis.) decision to ban for-profit earmarks is a "fig leaf, not real reform," Sen. Jim DeMint (R-S.C.) said Wednesday.

The senator, who has proposed a one-year moratorium on earmarks in the upper chamber, took to his Twitter account:

House Appropriations Chair David Obey's partial earmark ban wouldn't apply to 90% of earmarks. That's a fig leaf, not real reform.

Obey announced his move Wednesday morning as part of an effort to get out in front of Republicans on the issue. 

Government watchdogs have for years decried the use of earmarks, saying that they are wasteful and cause corruption.

Several lawmakers have pushed for reform for several years, but spending has ballooned under both Republican and Democratic Congresses.

But Republican earmark opponents have criticized the move, saying it won't be enough to truly rein in so-called "pork barrel" spending.

Senate Appropriations Committee Chairman Daniel Inouye (D-Hawaii) also panned the effort, saying that it is unfair to for-profit companies and assumes that non-profits are not corruptible.
