(CNN) - Mitt Romney, in remarks at a fund-raiser Tuesday, took a jab at President Barack Obama's campaign one day after financial filings revealed the president's re-election team had spent more money than it raised in July.
"We're a little wiser in our spending of dollars than the other side, apparently," Romney said, according to pool reports. "I'm not managing their campaign for them, but we're going to spend our money wisely. We're going to spend it to win."

The presumptive GOP presidential nominee made his comments while speaking at a private fund-raising event in Houston–one of two events in Texas for Romney on Tuesday. He later heads to Midland for a reception at the Petroleum Club. Combined, the events are expected to yield $6-7 million, the campaign said.
Obama's team took in $49.2 million in July but spent $59 million, according to the campaign's monthly filing with the Federal Election Commission released Monday. The campaign reported finishing the month with $87.7 million in the bank, down from $97.7 million at the beginning of July.
Reports also show that when combining the Obama campaign's haul with that of the Obama Victory Fund and the Democratic National Committee, the Obama re-election effort had about $124 million in the bank. The amount is considerably less than that of Romney's campaign and allies, which announced they had $185.9 million in the bank at the end of July.
The former Massachusetts governor also told the crowd, which included energy executives such as oil tycoon Harold Hamm, that he would be laying out a "comprehensive energy plan" in New Mexico by the end of the week. Romney, who said the plan would focus on "fossil-based fuels," asked the audience for input as he decides on the final details of the plan.
"I have a different approach, I think, generally to the role of government as it relates to energy, as well as other aspects of our economy," Romney said. "And it flows from a growing perspective I have throughout my life and frankly, during this campaign, about the power of individuals as opposed to government, individuals pursuing their interests and dreams."
Sen. Rob Portman of Ohio, Texas Lt. Gov. David Dewhurst and Senate candidate Ted Cruz of Texas were also at the Houston event.
