WASHINGTON, April 29 (Reuters) - U.S. President Donald Trump met on Tuesday with top officials from Chevron and other energy companies to discuss possible steps to calm energy markets if the blockade on Iranian ports continues for months, a White House official said on Wednesday.

The official added that the talks focused on US oil production, oil futures contracts, shipping and natural gas.

A Chevron spokesman said the company's CEO, Mike Wirth, attended the meeting to discuss global oil markets, which have been rocked by the US-Israeli war on Iran.

Axios was the first to report that the meeting was attended by Vice President J.D. Vance , Treasury Secretary Scott Bisent, White House Chief of Staff Suzy Wilms, Special Envoy Steve Wittkopf, and Jared Kushner, Trump's son-in-law.

The rise in oil prices poses a threat to Trump's Republican Party ahead of the midterm congressional elections in November.

The White House official said, "All the executives praised the actions taken by President Trump to unleash U.S. energy dominance, and said the president is taking all the right steps right now."

Last week, the Trump administration extended for 90 days an exemption from a shipping law known as the Jones Act to allow foreign-flagged vessels to transport goods such as petroleum products and fertilizers between U.S. ports.

This month, the administration invoked the Defense Production Act, which authorizes the Department of Defense (the Pentagon) and the Department of Energy to take actions, including purchases, to support the domestic energy sector in an effort to lower prices for consumers.

The White House official said Trump meets regularly with energy company executives to hear their views on domestic and global energy markets.
