President Donald Trump was ridiculed en masse Sunday after the purported ceasefire he claimed had been brokered between Russia and Ukraine fell apart within hours.

“What can you even say,” wrote investigative journalist and writer Ilya Lozovsky in a social media post on X.

Sunday morning, Trump took to social media to claim that an agreement had been reached between Russia and Ukraine to halt attacks on energy infrastructure.

“Effective immediately, there is an ENERGY CEASEFIRE in the War between Russia and Ukraine,” he wrote. “Both parties have agreed. Do not break it!”

Moments later, Ukrainian President Volodymyr Zelenskyy said of the purported agreement, “the ceasefire was news to me,” but said he would agree to halt attacks on Russian energy targets if Moscow followed suit.

Hours later, Zelenskyy said that Russian strikes on Ukrainian energy sites had continued despite Trump’s claim.

“There were strikes, unfortunately, with aerial bombs,” Zelenskyy said during his nightly video address, according to Reuters. “There were strikes on our energy infrastructure. Just now, there was a strike on the joint power and heating plant in the city of Kharkiv — hitting Kharkiv’s energy system.”

Former Republican congressman Adam Kinzinger sarcastically expressed shock that Trump’s purported agreement had proven to be false.

“What??? Trump lied???” Kinzinger wrote.

And Anne Applebaum, Pulitzer Prize-winning historian and journalist, issued Trump an especially harsh condemnation.

“Trump announces an energy ceasefire. Ukrainians learn about it from social media. Immediately, there are more Russian strikes on Ukrainian energy infrastructure,” Applebaum wrote. “The president lives in a fantasy world of his own construction.”
