President Donald Trump fired off insults toward Sen. Chris Murphy, D-Conn., in a Sunday post on Truth Social in response to the senator's criticism of his summit with Russian President Vladimir Putin.

The president described Murphy as "very unattractive (both inside and out)," "stupid," and "a lightweight," after the senator claimed "Putin got everything he wanted" during an appearance on NBC's "Meet the Press."

Murphy also described the meeting, which was held in Alaska on Friday to broker peace between Ukraine and Russia, as "a disaster," "an embarrassment for the United States" and "a failure."

‘OUR POSITION IS CLEAR:’ ZELENSKYY AND EU DISMISS CEDING UKRAINIAN LAND TO RUSSIA

Murphy shared a clip of his appearance on his X account, captioning the video with more criticism of Trump's meeting with Putin.

"The Putin-Trump meeting was a disaster, as predicted. Putin got everything he wanted: a photo op legitimizing his war crimes, no ceasefire, and no sanctions or new weapons for Ukraine. Trump's goal was to keep Putin happy. He succeeded," Murphy wrote.

Trump pushed back, asserting in his Truth Social post, "The very unattractive (both inside and out!) Senator from Connecticut, Chris Murphy, said ‘Putin got everything that he wanted.’ Actually, ‘nobody got anything,’ too soon, but getting close. Murphy is a lightweight who thinks it made the Russian President look good in coming to America.

"Actually, it was very hard for President Putin to do so. This war can be ended, NOW, but stupid people like Chris Murphy, John Bolton, and others, make it much harder to do so," he added.

ZELENSKYY ARRIVES IN WASHINGTON, DC FOR TRUMP MEETING, URGES LASTING PEACE WITH RUSSIA

Ukrainian President Volodymyr Zelenskyy and seven European leaders will meet with Trump in Washington, D.C. on Monday to continue seeking an end to the Russia-Ukraine war.

"Big day at the White House tomorrow. Never had so many European Leaders at one time. My great honor to host them!!!" Trump said in a separate Sunday night post on Truth Social.

In a third post on Sunday, Trump said Zelenskyy "can end the war with Russia almost immediately, if he wants to, or he can continue to fight." 

Trump continued, "Remember how it started. No getting back Obama given Crimea (12 years ago, without a shot being fired!), and NO GOING INTO NATO BY UKRAINE. Some things never change!!!"

Ukrainian President Volodymyr Zelenskyy confirmed his arrival in Washington, D.C., on Sunday ahead of a meeting with President Donald Trump to discuss an end to the war with Russia.

"I have already arrived in Washington, tomorrow I am meeting with President Trump. Tomorrow we are also speaking with European leaders. I am grateful to @POTUS for the invitation. We all share a strong desire to end this war quickly and reliably. And peace must be lasting," Zelenskyy wrote, in part, on X on Sunday.

Zelenskyy will be bringing a group of European leaders to the Monday meeting, and Trump said on Truth Social it is a "great honor to host them all."

EUROPEAN LEADERS WILL JOIN TRUMP-ZELENSKYY MEETING, SIGNALING SOLIDARITY WITH UKRAINE

Zelenskyy said this meeting must be different from past discussions on how to achieve peace with Russia, which allowed Moscow to take over Crimea and part of Donbas in 2014. 

He also noted that "so-called ‘security guarantees’" given to Ukraine in 1994 in the years after the fall of the Soviet Union did not work.

The Ukrainian president said his country would not tolerate another temporary truce, maintaining that only enforceable guarantees from the U.S. and Europe could prevent Moscow from launching future attacks.

'OUR POSITION IS CLEAR:' ZELENSKYY AND EU DISMISS CEDING UKRAINIAN LAND TO RUSSIA

In his post on X, Zelenskyy highlighted some of the recent "successes" by Ukrainian forces, emphasizing his assurance that Kyiv can and will defend its territory with continued Western backing. 

"Ukrainians are fighting for their land, for their independence. Now, our soldiers have successes in Donetsk and Sumy regions. I am confident that we will defend Ukraine, effectively guarantee security, and that our people will always be grateful to President Trump, everyone in America, and every partner and ally for their support and invaluable assistance," he maintained.

While Zelenskyy expressed his gratitude to Trump, America and European allies for the support, he also said he hopes "joint strength" will push Russia to end the war it started more than three years ago.

"Russia must end this war, which it itself started. And I hope that our joint strength with America, with our European friends, will force Russia into a real peace. Thank you!," the post concluded.

The push comes after Russian President Vladimir Putin reportedly demanded that Ukraine withdraw from two eastern regions during a summit with Trump in Alaska on Friday.

Trump appeared to show support for Putin's request in a post on Truth Social on Sunday night, writing that Zelenskyy does have the ability to "end the war with Russia."

"President Zelenskyy of Ukraine can end the war with Russia almost immediately, if he wants to, or he can continue to fight. Remember how it started. No getting back Obama given Crimea (12 years ago, without a shot being fired!), and NO GOING INTO NATO BY UKRAINE. Some things never change!!!" he wrote.

Zelenskyy has repeatedly stated that Ukraine is not giving up any territory.
