One of Barack Obama's top campaign cash bundlers, former New Jersey Governor and US Senator Jon Corzine, is being investigated by the FBI and Department of Justice for $1.2 billion that is missing from his company MF Global. Some of that missing cash may be sitting in Colorado US Senator Mark Udall's re-election account and Compass Colorado President Tyler Q. Houlton is calling on Udall to return the tainted tender.

Reports The Hill:

Jon Corzine, former CEO of MF Global, has given tens of thousands of dollars to the Democratic Party in recent months, putting Democratic lawmakers in awkward positions ahead of Corzine’s subpoenaed appearance before a House committee next week.  

The House Agriculture Committee wants Corzine to explain the financial collapse of MF Global and what may have happened to clients’ investments.

RNC Chairman Reince Priebus has called on President Obama to return the $500,000 Corzine had bundled for Obama's campaign so far this year.  

In Udall's case, he has accepted $4,600 in contributions, the legal maximum at the time of the donation, from the former lawmaker.

With Corzine under criminal investigation for missing money, all of his donations become tainted. Udall, who likes to portray himself as someone willing to hold Wall Street accountable, will have some tough decisions to make.

“With a criminal investigation looking into Jon Corzine’s shady Wall Street firm, Mark Udall should immediately return Corzine’s tainted campaign cash,” said Tyler Q. Houlton, president of Compass Colorado. “Mark Udall may pretend to stand up to Wall Street bankers, but his campaign war chest suggests otherwise.”

Corzine is quickly becoming an enormous issue for Democrats. They are trying to portray themselves as supportive of the "99%" and not the "1%," yet their campaign donations sing a different tune than their political messaging. It is donations like Corzine's nearly $5,000 to Udall and data showing the Democrats accepting $197 million from the securities and investment industry since 2006 that make that all the harder.

The question for Senator Udall at this point is: Is being tied to corrupt politician and Wall Street banker Jon Corzine worth $4,600?
