The $410 billion spending bill that President Obama expected to sail through Congress is now coming under intense fire for thousands of earmarks that even some senators admit look like pay-to-play politics.

On Monday, Sen. Tom Coburn, R-Okla., told fellow senators the “outright greed” and the political motivation behind many earmarks made him “want to vomit.”

When it appeared Coburn might be blocked from offering earmark-curtailing amendments to the omnibus spending bill, he complained: “We’re not supposed to take out things that are obviously quid pro quo in terms of earmarks and campaign contributions.”
