Sen. John McCain, the likely Republican presidential nominee who has linked his political future to U.S. success in Iraq, was in Baghdad on Sunday for meetings with Iraqi and U.S. diplomatic and military officials, a U.S. government official said.
Details of McCain's visit, which had been anticipated, were not being released for security reasons, the U.S. Embassy said. It was unclear who he met with; no media opportunities or news conferences were planned.
McCain, a strong supporter of the U.S. military mission in Iraq, is believed to be staying in the country for about 24 hours.
"Senator McCain is in Iraq and will be meeting with Iraqi and U.S. officials," said Mirembe Nantongo, spokesman for the U.S. Embassy in Baghdad.
Meanwhile, in the US, Obama and Clinton are at each other's throats. In a conference call with reporters Sunday, Obama's top aides reiterated their demand for more information from the Clintons on four fronts: tax returns; earmark requests; White House records; and a list of library donors. Obama campaign strategist David Axelrod was especially critical of the ethics of the Clinton campaign, telling reporters, "they are are literally willing to do anything" to win.

For their part, the Clinton campaign has signaled their intention to attack Barack Obama's business dealings with indicted businessman Tony Rezko.
