(CNN) - Mitt Romney on Wednesday weighed in on two scandals dogging the Obama administration, saying if he were president he would "clean house" and replace certain personnel with those who put "interests of the nation ahead of personal play time."
Asked about the recent U.S. Secret Service controversy as well as the General Services Administration scandal, Romney said on Laura Ingraham's radio show that he would bring "people into leadership of these organizations that are obviously committed to living by the highest standard of integrity."

His comments come as more details become public about reports of Secret Service and U.S. military bringing prostitutes to their hotel rooms while on a trip with the president to Colombia last week.
"Obviously everyone is very, very disappointed in these stories, very uncharacteristic of the Service," Romney said in a separate radio interview with WTVN, a local station in Ohio. "And I think it will be dealt with in as aggressive a way as is possible given the requirements of the law."
Romney said he believes the right "corrective" action will be taken and remains confident in the Secret Service, an agency that has offered the candidate protection on the campaign trail since early February.
Also on Wednesday, the Senate will hold further hearings on the GSA spending scandal, marking the third day in a row Congressional lawmakers have questioned the agency's decision to host an $800,000 Las Vegas conference on the taxpayers' dime.
Romney described the unfolding controversy as an embarrassment for the president, though adding there will be bad actors "from time to time" in any large enterprise and that it's up to the leaders to set the right kind of example.
