When former president Joe Biden took over from Trump in 2021, he removed the designation that Trump had signed near the end of his first term.
Biden's move came in response to concern from aid groups that they would need to pull out of Yemen as they are obliged to deal with the group, which is effectively the government in vast areas including the capital Sanaa.
Weeks after the Israeli war on the Gaza Strip broke out on October 7, 2023, the Houthis began launching attacks on shipping in the Red Sea and Gulf of Aden linked to Israel, in support of the Palestinians.
Biden administration last year put the Houthis -- formally known as Ansar Allah -- back on the list of "specially designated global terrorist" groups.
That slightly less severe classification still allowed for humanitarian aid to reach the war-torn country.
The Trump administration's Wednesday move aims to reimpose the more restrictive label of foreign terrorist organizations.
Trump's executive order claimed the Houthis had "launched numerous attacks on civilian infrastructure, including multiple attacks on civilian airports in Saudi Arabia," in addition to firing "more than 300 projectiles fired at Israel since October 2023."
The order may take several weeks to come into effect.
