Trump’s envoys Steve Witkoff and Jared Kushner are expected to meet with Russian President Vladimir Putin in Moscow on Saturday before traveling to Kyiv on Sunday to meet with Ukrainian President Volodymyr Zelensky, according to reports. The trip would mark their first visit to Ukraine and comes as the Trump administration renews efforts to mediate an end to the conflict.

The Russian state news agency TASS first reported that the two U.S. representatives would visit both countries over the weekend, although it did not identify its source. Kremlin spokesman Dmitry Peskov declined to confirm the schedule, telling reporters that the Kremlin would announce the contacts when appropriate.

Zelensky said Thursday that Trump’s representatives were expected to visit Moscow and Kyiv in the coming days. U.S. and Ukrainian officials have reportedly been discussing the Kyiv portion of the trip for months.

However, security concerns have created uncertainty surrounding the visit. Russia and Ukraine have continued launching attacks against one another, and the United States is seeking assurances that the envoys can safely travel between the two capitals. Reuters reported that Washington has sought commitments from Ukraine not to strike Moscow during the visit while asking Russia to avoid attacks on Kyiv.

Witkoff and Kushner last met with Putin in Moscow in January, holding roughly four hours of late-night talks at the Kremlin. They have made multiple trips to Russia but have not previously traveled to Ukraine.

The diplomatic effort faces significant obstacles. Moscow continues to demand that Ukraine surrender territory claimed by Russia and abandon its aspirations to join NATO, while Kyiv has rejected those conditions as unacceptable.

Putin said Thursday that there was a possibility of reaching an agreement to end the war, although he acknowledged that major obstacles remain. Peskov similarly said negotiations could eventually produce a settlement but that the necessary conditions for an agreement do not currently exist.

The last U.S.-mediated Russia-Ukraine talks took place in February before the outbreak of the U.S.-Israeli war with Iran interrupted the diplomatic process. The planned meetings in Moscow and Kyiv represent a renewed attempt by the Trump administration to bring both sides back toward negotiations.
