Romney defends offshore investments

Following a week of blistering attacks from Democrats over Mitt Romney's personal, offshore investments, the presumptive GOP presidential nominee responded Monday and denied any wrong-doing in his finances.

Saying his foreign investments have been held by a blind trust and managed by a trustee, Romney emphasized he has no knowledge of where his money is being placed.

"I don't manage them. I don't even know where they are," Romney said in an interview on Radio Iowa.

Obama's campaign recently seized on a report in the magazine "Vanity Fair," which called Romney a "remarkable financial acrobat," with accounts and investments in several places considered tax havens for Americans - Bermuda, the Cayman Islands and Switzerland.

Romney countered his rival's re-election campaign, which has also been hammering the candidate to release more than the two years' worth of tax documents that Romney has already made public.

While Team Obama hasn't directly charged Romney with tax evasion, they suggest the millionaire may be hiding important details about his finances by not disclosing multiple years of returns.

Romney, however, reiterated that there is no violation of tax law.

"That trustee follows all U.S. laws. All the taxes are paid, as appropriate. All of them have been reported to the government. There's nothing hidden there," the candidate said.

Federal campaign law does not require candidates to release tax returns, but it does require candidates to file annual financial disclosure paperwork, which Romney has done in addition to the taxes he has released.

The presumptive GOP presidential nominee argued Monday that his opponent was simply trying to cause a distraction.

"I understand the president's going to try to do anything he can to divert attention from the fact that his jobs record is weak and he has no plan to make things better," he said.
