(CNN) – Call it a proxy war for their more significant differences: a volley of press releases from the political forces supporting President Barack Obama and Mitt Romney.
It began with a Thursday report that Romney's former financial firm allowed employees to buy a special type of stock in companies owned by the firm and include that stock in their retirement portfolios.

Following the report, which was published by the Wall Street Journal, Democrats requested Romney release additional tax documents, which could shed light on some investment deals which Romney might have received. In January, his campaign released tax returns for 2010 and estimates for 2011, the two most recent years available - some 500 pages of documents.
"Today's report raises additional questions about Gov. Romney's manipulation of the tax laws," said Ben LaBolt, an Obama spokesman, on Friday. He questioned if Romney "may have engaged in questionable maneuvers to drive up the value of his IRA.
"Governor Romney could help answer the questions that have been raised by releasing his tax returns beginning with the year he became a corporate buyout specialist," LaBolt continued.
The Romney campaign countered by calling on Obama to release administration documents.
"The Obama campaign is playing politics, just as he's doing in his conduct of foreign policy," Andrea Saul, a spokeswoman for Romney, told the National Journal in a story published Friday. "Obama should release the notes and transcripts of all his meetings with world leaders so the American people can be satisfied that he's not promising to sell out the country's interests after the election is over."
The Romney campaign did not respond to a request from CNN to confirm the statement. Romney has been critical of the president for asking the Russian president for "space" on a missile defense project in a moment caught on an open microphone.
The Democrats responded by saying the Romney campaign request demonstrated "remarkable naiveté about foreign policy."
"For example, does Governor Romney think we should release all the notes and transcripts of the President's conversations with our allies, such as the Israelis and Europeans, tipping our hand to Tehran about every last element of our strategy to prevent Iran from getting a nuclear weapon?" Colin Kahl, a former Deputy Assistant Secretary of Defense under Obama, said in a statement circulated by the DNC and Obama campaign.
"Our friends around the world need to trust that they can speak with the President of the United States in confidence, and that these conversations will not be politicized during an election," he continued.
