; On Sunday, Sununu gave the same explanation for using the government car that he had offered for using government planes -- that he must be able to communicate instantly with the White House in the interest of national security. After the controversy two months ago over White House Chief of Staff John Kerry 's use of private aircraft for private travel , President Bush instituted new travel rules forbidding the practice . Now Sununu has again created what the President calls an " unprecedented problem " by using a government limousine to travel to New York on strictly personal business . Replying to critics of the New York trip , Sununu vowed he would not take advice from " self- styled experts " on how he travels and explained that he took the car so as to be able to communicate instantly with the White House in the interest of national security .
