Republicans have spent the last day attacking the Obama administration after a staffer was revealed to have given paid speeches to a company which traded with Iran. They even released an attack ad on the subject — which would all be pretty embarrassing if, errr, Mitt Romney was revealed to have part-owned a company which does business with regime!

Romney’s financial disclosures reveal that, up until last May, he owned thousands of dollars of shares in Abbott Laboratories, who trade with Iran and whose CEO is a big Republican donor. The stock was the only stock he listed separately from other trusts on his tax returns.

How convenient!
