Following her announcement of a truce in the city of Oleshky last month, First Lady Melania Trump will host delegates from Russia and Ukraine at the White House on Thursday.

The first lady's office announced on Tuesday that "First lady Melania Trump will personally bring representatives of Russia and Ukraine, two nations actively at war, together at the White House," hailing the short truce as a "unprecedented diplomatic initiative by an American first lady."

According to Russian and Ukrainian officials, Trump will receive Russian Ombudsman Yana Lantratova and Ukrainian Ombudsman Dmytro Lubinets.

Lantratova and Lubinets had already met, most notably last week during the Oleshky truce. Although none has previously participated in high-level talks with the US delegations, those who have are anticipated to accompany them.

The Kremlin said Wednesday that Kirill Dmitriev, a skilled negotiator and special envoy of Russian President Vladimir Putin, will accompany Lantratova. David Arakhamia, a legislator and negotiator, would accompany Lubinets to the conference, according to Ukrainian media.

In an interview with CNN while traveling to Washington, DC, Dmitriev stated that his "deep belief in cooperation between the US and Russia" was a major driving force behind his work as an interlocutor.

"I'm focused on US-Russian relations in general, and I'm always trying to help if there's a humanitarian situation to solve," he stated.

The first lady's senior adviser, Marc Beckman, most recently expressed gratitude to Dmitriev for his "leadership in establishing and sustaining the ceasefire in Oleshky." Dmitriev "had a lot to do with [the release] happening," according to US special envoy Steve Witkoff, who presented Dmitriev to Stephen Hubbard, a liberated US citizen who was "wrongfully detained" according to the US State Department, last month.

During her husband's second administration, Trump has maintained a much lower role. She will also speak about the limited truce. She has, however, avoided some of the job's more conventional responsibilities in favor of working behind the scenes on more significant policy initiatives.

The first lady was given the Order of Princess Olga, a Ukrainian civil decoration, by Ukrainian President Volodymyr Zelensky on Wednesday. It honors her "active human rights and charitable work aimed at rescuing Ukrainian children and citizens" as well as her "significant personal contributions" to humanitarian aid for Ukraine.

On October 23, Trump declared that she had negotiated a localized truce to enable the compassionate evacuation of senior citizens from Oleshky. October 27 marked the start of the brief truce, which ended on Sunday. One man who hadn't seen his wife in 1,711 days was among the hundreds of people who were evacuated from Oleshky and sent back to Ukraine.

Andrii Sybiha, Ukraine's foreign minister, stated last month that the humanitarian situation in Oleshky had gotten so bad that some locals were forced to eat grass and weeds without access to electricity, clean water, or medicine.

According to Trump's staff, she served as the "exclusive intermediary," working directly with Russian and Ukrainian leadership using channels she had previously set up while trying to reconnect children who had been separated from their families during the conflict.

Trump wrote on X, "The mission was a success, delivering critical aid to the region and enabling the evacuation of nearly 800 people." She also expressed her hope that Oleshky "serves as a foundation for lasting peace between both nations."

According to the first lady's office last month, she learned of Oleshky's situation during a private conversation at the 81st United Nations General Assembly in New York.

The Vatican claims that earlier in October, while in the hospital recuperating from lung cancer surgery, Pope Leo spoke with Russian President Vladimir Putin over the phone about the humanitarian situation in Oleshky, as CNN previously reported. Putin "supported" the Vatican's plan to ease the situation, according to the Kremlin.
