U.S. President Joe Biden and King Salman of Saudi Arabia discussed energy supplies in the face of soaring fuel prices and developments in the Middle East, including Iran and Yemen, in a telephone call on Wednesday. The two leaders committed to ensuring the stability of global energy supplies, the White House said in a statement. Last week, OPEC+ agreed to stick to moderate rises in its oil output, with the group struggling to meet existing targets and wary of responding to calls on its strained capacity for more crude from top consumers to cap surging prices. High oil prices are a risk to the Biden administration ahead of November's congressional elections in which his fellow Democrats will defend slim majorities in the Senate and U.S. House of Representatives. A U.S. source familiar with the call said, "Saudi Arabia has historically played a vital role in ensuring global energy markets are well supplied to support strong and resilient economies. Oil has also been supported by the tension in Ukraine as Russia has put more than 100,000 troops on its borders.
