Trump also criticized Ukraine's Zelenskyy for his comments on the war.
President Donald Trump on Sunday agreed to delay the deadline for a 50% tariff on the European Union. The president also weighed in on Russia's escalated, overnight attacks on Ukraine while criticizing both Putin and Zelenskyy.
Trump also continued to criticize Harvard on Sunday, questioning the university's transparency and demanding that it reveal its international students' identities.
On Capitol Hill, the House this week passed the "One Big Beautiful Bill Act" to fund Trump's domestic agenda. It now heads to the Senate, where it will likely be changed.
Vice President JD Vance, while in Rome for Pope Leo XIV's inaugural mass, "passed along a letter to the Pope from the president and from the first lady extending their warm wishes and inviting them to the White House as soon as they possibly can come," according to the White House.
White House press secretary Karoline Leavitt was asked on Monday if President Donald Trump has spoken to former President Joe Biden directly following Biden's prostate cancer diagnosis.
"Not to my knowledge, I don't believe they have spoken, but I'm sure the president would be open to doing that," Leavitt said. "I spoke to him last night about the former president's cancer diagnosis and the statement that he put out was the initial reaction he had with me on the phone as well."
Trump wrote on his conservative social media platform on Sunday, "Melania and I are saddened to hear about Joe Biden's recent medical diagnosis. We extend our warmest and best wishes to Jill and the family, and we wish Joe a fast and successful recovery."
White House press secretary Karoline Leavitt, at Monday morning's briefing, told reporters the public can expect to hear from President Donald Trump or the White House following his calls today regarding the Russia-Ukraine war.
Trump will be speaking with Russia's Vladimir Putin at 10 a.m. ET. Leavitt said Trump is planning to call Ukrainian President Volodymyr Zelenskyy immediately after that conversation.
"I don't want to get ahead of those very important conversations, but of course you will hear directly from the president or me after those calls conclude today, so you can expect that," she said.
ABC News Senior Political Correspondent Rachel Scott pressed Leavitt if Trump would set a new deadline for peace talks on the call, but Leavitt repeated she wouldn't speak ahead of Trump on any specific timeline.
"His goal is to see a ceasefire and to see this conflict come to an end, and he's grown weary and frustrated with both sides of the conflict," she said.
Asked if Trump is open to meeting with Putin, Leavitt said she believed Trump "would certainly be open to that but let's see how this call goes today."
President Donald Trump early on Monday said he would call for an investigation into musician Bruce Springsteen's endorsement of former Vice President Kamala Harris' presidential run.
"I am going to call for a major investigation into this matter," Trump said in a post on his Truth Social network. "Candidates aren't allowed to pay for ENDORSEMENTS, which is what Kamala did, under the guise of paying for entertainment."
Springsteen preformed at Harris' campaign appearance in Georgia in October. Trump in his Monday post asked how much Harris had paid the musician.
His call for a probe followed a back-and-forth between the president and the songwriter last week.
As he took the stage in Manchester, England, last Wednesday, Springsteen had called "upon the righteous power of art, of music, of rock and roll, in dangerous times."
"In my home, the America I love, the America I've written about, that has been a beacon of hope and liberty for 250 years is currently in the hands of a corrupt, incompetent, and treasonous administration," Springsteen said.
He added, "Tonight we ask all who believe in democracy and the best of our American experiment to rise with us, raise your voices against authoritarianism and let freedom ring!"
Trump in a subsequent post on Truth Social called Springsteen "overrated" and said he shouldn't speak about America "until he gets back into the Country."
