The conservative blogosphere and media megaphones are trumpeting “news” that President Barack Obama’s trip to India will cost U.S. taxpayers $200 million a day, but there’s no basis in fact for the reports, and history suggests that they’re false.

First, the source of the report: an unidentified Indian government official. The Press Trust of India, a news agency, reported this week that Obama’s three-day trip to India would cost $200 million a day and include 3,000 people.

“The huge amount of around $200 million would be spent on security, stay and other aspects of the presidential visit,” a top official of the Maharashtra Government privy to the arrangements for the high-profile visit said, according to the news agency.

The report was posted prominently on the conservative website Drudge Report. Conservative bloggers such as Michelle Malkin posted it without question. Conservative commentator Glenn Beck multiplied it for the rest of Obama’s four-country trip, saying it will cost taxpayers $2 billion. And on and on.

The Indian news organization also reported that the United States was sending 34 warships to protect Obama.

Official response: The White House says it won’t reveal the costs of security for a president’s trip, which is long-standing policy. But aides said the $200 million figure was greatly exaggerated. Some previous international trips for President Bill Clinton averaged about $10 million a day.

The Pentagon said the report about warships was absurd.

“I will take the liberty this time of dismissing as absolutely absurd this notion that somehow we were deploying 10 percent of the Navy, some 34 ships and an aircraft carrier, in support of the president’s trip to Asia,” Pentagon spokesman Geoff Morrell said. “That’s just comical. Nothing close to that is being done.”
