President Donald Trump talks to reporters as he departs for travel to Indianapolis, Indiana from the White House in Washington, U.S., April 26, 2019.

President Donald Trump on Friday said he "called up" OPEC and told the producer group to take action to bring down fuel costs, making a dubious claim that gasoline prices are already falling.

Crude futures extended earlier losses after Trump's statement. U.S. West Texas Intermediate crude was down 3.4% at $63.01 per barrel, while international benchmark Brent crude fell 3.2% to $71.98.

"The gasoline prices are coming down. I called up OPEC. I said, 'You've got to bring them down. You've got to bring them down,' and gasoline's coming down," Trump told reporters en route to a National Rifle Association event in Indianapolis.

In fact, the national average for a gallon of regular gasoline is $2.883 per gallon, up from $2.877 a day ago and $2.839 a week ago, according to AAA. Wholesale U.S. gasoline prices have ticked lower in recent days, but are still up about 10% from a week ago and nearly 7% from a month ago.

It was not immediately clear whether Trump meant that he had contacted the OPEC Secretariat in Vienna, or whether he was referring to OPEC members and close U.S. allies like Saudi Arabia and the United Arab Emirates. OPEC could not immediately be reached for comment.

The Wall Street Journal reported that OPEC's Secretary General Mohammed Barkindo has not spoken to Trump, citing a source. Saudi officials also told the Journal that Trump has not discussed lowering prices with them.
