President Barack Obama’s senior adviser for his reelection, Robert Gibbs, said on Sunday that Mitt Romney, the presumptive Republican presidential nominee embarrassed the United States during his trip last week to London.

Gibbs said that Romney was thinking aloud when he said that London might not have been ready for the start of the Olympic Games and he said that many voters in the U.S. are wondering if Romney is ready to lead the nation in front of the rest of the world.

Romney was greeted with numerous harsh headlines in the British press after his comment that the London Games had some disconcerting problems. Romney was in charge of organizing the Salt Lake City 2002 Winter Olympics and on Wednesday said it was too soon to tell if the organizers in London were ready for the Games to start.

Following his comments, Romney never repeated the criticism again. He did however, offer great praise for England.

Gibbs said it was very bad for Romney to travel overseas to visit the country’s strongest ally and question if the country was ready for the Olympics after they prepared for years for them. He called Romney’s actions embarrassing for the U.S.

A senior advisor for the Romney campaign, Kevin Madden countered the assertions by Gibbs saying a simple gaffe will not determine the outcome of the election. Madden said the believes the headlines in London for a day will not be important overall with voters when it comes to talking about the economy or jobs.
