WASHINGTON - After a difficult week that sparked a burst of Republican hand-wringing, Mitt Romney's campaign team fought back on Monday against a report of disarray in his inner circle and promised to retool his message with more specifics of his policies.

Senior adviser Ed Gillespie struck an optimistic tone despite the Republican worries, saying US President Barack Obama's post-Democratic convention bounce in polls had faded and the race for the White House had tightened again ahead of the Nov. 6 election.

Romney dismissed a Politico report on Sunday night that portrayed a chaotic and sometimes confused Romney campaign team led by chief strategist Stuart Stevens.

"I've got a terrific campaign," Romney said in an interview with the Spanish-language television network Telemundo, adding there would be no changes to his top staff.

"My senior campaign people work extraordinarily well together," he said. "These process stories really take away from what's really of concern to the American people."
