Hizbollah is fighting Isis (Islamic State) in Syria on behalf of Syrian President Bashar al-Assad, but Lebanon is not fighting Hizbollah. It was not clear whether Trump was confused about that, or simply misspoke.
The United States has long condemned Hizbollah, a sprawling organisation with military and political arms, and considers it a threat to Mideast stability. The group is Lebanese, but receives backing from Iran. And, in various forms, it has been a fact of political life in Lebanon for decades.
Hariri, a Saudi-backed Sunni, has a delicate power-sharing relationship with Shia Hizbollah, which with its allies effectively controls Lebanon's powerful Parliament. The country's President, former General Michel Aoun, is backed by Hizbollah.
The United States and Lebanon essentially agree to disagree about the value of political partnership with Hizbollah, which Washington considers a terrorist group. Hizbollah brought down a previous Lebanese government headed by Hariri, son of assassinated Lebanese political lion Rafik Hariri, and he governs with the knowledge that the group might be able to do it again.
Speaking to reporters later, Hariri said that Trump had been well informed about Hizbollah during their meeting. He stepped carefully around the question of whether Trump did not understand the group's political role and power.
"In Lebanon we are fighting Isis and al-Qaeda. Hizbollah we have, you know, in the Government. And we have an understanding with Hizbollah," Hariri said. "It is important to have this consensus. We have good dialogue with Hizbollah. They are in the Parliament."
Hariri is in Washington to rally support in the Administration and Congress for economic and diplomatic support as Lebanon copes with more than a million refugees from the Syrian war next door.
