Another Obama appointment runs into tax trouble

What is it about President Barack Obama’s appointees and taxes? Does the vetting process not ask a simple question like "do you pay your taxes?"

Doesn’t look like it. Another one is in tax trouble.

Obama’s trade rep pick owes $10,000 in taxes – Former Dallas, Texas, Mayor Ron Kirk, who is President Obama’s nominee to be the U.S. trade representative, owes nearly $10,000 in taxes. He’s the fourth Obama pick that has come under fire for tax issues.
