During a radio interview on Tuesday, the presumptive GOP nominee declined an opportunity to ask his supporters to stop, saying his campaign didn’t “believe in unilateral disarmament.”

Team Romney drew flack last week after its campaign bus reportedly circled the site of the president’s economic address in Cleveland honking its horn repeatedly to taunt the Obama’s supporters.

Obama campaign spokeswoman Lis Smith, on Twitter, blasted the move as “juvenile.”

“If campaigns are a reflection of their candidates, what do the Romney campaign’s antics say about Mitt Romney?” Smith tweeted.
