(CNN) - John McCain — whose campaign launched an ad this week blaming Barack Obama for high prices at the pump — said Wednesday President Bush's new push for offshore oil drilling deserves the credit for the recent drop in crude oil prices.
"In case you missed it, soon as the President announced that we were going to end the moratorium on offshore drilling the price of a barrel of oil went down $10," the presumptive Republican nominee said at a Wilkes-Barre, Pennsylvania town hall.
Crude oil prices are down about $20 a barrel from their record-setting intra-day high of $147.27 a barrel back on July 11.
President Bush announced on July 14 he was lifting executive ban on offshore drilling, although Congress has yet to act on his call to lift its own drilling ban.
Asked about McCain's comments today, White House Press Secretary Dana Perino replied, "I don't know that we fully deserve the credit, but I do think in was important to send a signal to the market that we are serious about moving forward."
Earlier this week, McCain's campaign released a new television spot blaming Barack Obama's opposition to offshore drilling for the nation’s rising gas prices.
