The United States’ Syrian Kurdish allies are in Washington this week in a last-ditch effort to salvage the fraying partnership.

Ilham Ahmed, the head of the Syrian Democratic Forces’ political wing, hopes to convince Congress and the Donald Trump administration to prevent Turkish airstrikes against the group. She is set to meet tonight with the co-sponsors of bipartisan sanctions Turkey legislation, authored by Sens. Chris Van Hollen, D-Md., and Lindsey Graham, R-S.C, before testifying Wednesday at a House Oversight subcommittee hearing on US policy in Syria along with military and humanitarian experts.

Her list of demands, Al-Monitor first reported Sunday, includes a request that the Trump administration help secure a strategic road where Turkish-backed proxies reportedly killed a prominent Kurdish politician last week. Ahmed’s Syrian Democratic Council also wants Trump to keep US bases in Kobani, Hasakah, Shadade, Deir ez-Zor, Tabqa and Ramelan. She is also expected to ask that the SDF be part of the United Nations-backed negotiations to end the eight-year Syrian civil war.

The visit comes as the United States has already withdrawn most of its troops from northeast Syria. Trump, however, is reportedly weighing keeping about 200 troops in the area to stop oil fields from falling into the hands of the Bashar al-Assad regime.
