WASHINGTON (Reuters) - Republican candidate Mitt Romney accused President Barack Obama on Wednesday of being "intent on hiding" his true positions, in a growing war of words between the two men who are increasingly likely to face off in November's presidential election.
Romney slammed Obama a day after winning three presidential primaries and moving closer to finally clinching the Republican nomination.
The former Massachusetts governor cited remarks by Obama to Russian President Dmitry Medvedev last week that embarrassed the U.S. president when they were caught on camera. Obama assured the Russian leader that he would have "more flexibility" to work on missile defense after the November 6 election.
"He is intent on hiding. You and I will have to do the seeking," Romney said in a speech to a conference of news executives. Romney seemed relaxed throughout his speech, which focused exclusively on Obama rather than his Republican rivals.
Romney was speaking at the same conference where Obama attacked him on Tuesday in comments that gave a clear signal that the general election campaign is effectively under way.
Obama mentioned Romney by name, a move he had avoided before then, and criticized him for supporting a Republican budget plan that would make stark cuts in Medicare and other programs for the poor and elderly.
In a wide-ranging speech hitting Obama's record in office, Romney answered the criticisms.
"I looked at what the president said. There were just so many things that I found to be distortions and inaccuracies, it's hard to give a full list," he said.
"President Obama came here yesterday and railed against arguments no one is making and criticized policies no one is proposing. It's one of his favorite strategies - setting up straw men to distract from his record."
After his election victories in Washington, D.C., Maryland and Wisconsin, Romney now has more than half the 1,144 delegates needed to win the nod from his party.
