Democratic Rep. Ro Khanna said Israeli settlers detained him for more than an hour while he was visiting the West Bank.
Khanna said members of the Israel Defense Forces spoke with the settlers and moved a car to block the road.
A spokesperson for the congressman confirmed the details, and a photojournalist also witnessed the interaction.
Khanna's visit to the West Bank took place during the congressional recess.
The Israel Defense Forces were contacted for comment.
U.S. politicians from both sides of the aisle have visited the West Bank since the war in Gaza was sparked by a massive attack on Israel on Oct. 7, 2023.
House Speaker Mike Johnson visited the territory in September 2025 and dined with Israeli Prime Minister Benjamin Netanyahu.
Democrats Chris van Hollen and Jeff Merkley, of Maryland and Oregon respectively, toured the region in August 2025.
Several nations that have supported Israel criticized the country after Israel Defense Forces troops fired "warning shots" near a group of diplomats visiting the territory in May 2025; the delegation included representatives from the European Union, Japan and Russia, and the IDF said the shots were fired after the group wandered off an approved route and entered a restricted area.
The United Nations said in May that more than 1,000 Palestinians have been killed in the West Bank and eastern Jerusalem since the war began.
Journalists met Palestinian residents and Israeli activists in the West Bank who said violent attacks by Israeli settlers have increased significantly since the war in Gaza began, including attacks that have driven people from their land, and that Israel has continued to expand its settlements in the territory.
Israeli soldiers accused of harming Palestinians in the West Bank were indicted in fewer than 1% of cases based on 2,427 complaints alleging wrongdoing between 2016 and 2024, according to Israeli rights group Yesh Din.
More than 700,000 Israelis live in the occupied West Bank and east Jerusalem, territories captured by Israel in 1967 from Jordan and sought by the Palestinians for a future state, and about 15% of the settlers are Americans.
The United Nations calls Israeli settlements in the West Bank illegal, and five long-time U.S. allies jointly imposed sanctions on two senior Israeli officials they accused of "inciting violence against Palestinians in the West Bank;" Secretary of State Marco Rubio condemned the sanctions and called for their reversal.
