Millions of Americans grumbled April 15 as they rushed to file their taxes on time.

Some, including this author, paid online; others stood in line. And some used Tax Day as an opportunity to take a jab at Nevada’s Democratic Sen. Harry Reid.

Yes, that’s a photo of former Massachusetts Gov. Mitt Romney standing in line to file his taxes.

“Hey @SenatorReid here’s a shot of @MittRomney paying taxes,” his son Josh Romney tweeted. “Does it every year. It’s how you get your paycheck.”

Romney’s taxes became a major focus of the 2012 presidential elections as President Barack Obama and his allies repeatedly suggested the Republican presidential candidate hadn’t paid “his fair share.”

Reid helped in these attacks, using the floor of the U.S. Senate to accuse Romney of being a tax cheat.

“He has refused to release his tax returns, as we know. If a person coming before this body wanted to be a cabinet officer, he couldn’t be if he did the same refusal Mitt Romney does about tax returns,” Reid said in 2012. “So the word’s out that he hasn’t paid any taxes for 10 years. Let him prove that he has paid taxes, because he hasn’t.”

“We already know from one partial tax return that he gave us, he has money hidden in Bermuda, the Cayman Islands and a Swiss bank account. Not making that up, that’s in the partial year that he gave us,” Reid said. “Mitt Romney makes more money in a single day than the average middle-class family makes in two years–or more.”

Romney later released his tax returns showing that he had indeed been paying the U.S. government all along. Reid never retracted his accusations or revealed his supposed source of information.
