On Sunday, U.S. president Donald Trump criticised his former national-security advisor and suggested that the U.S. should not worry about Russian President Vladimir Putin in light of Moscow’s continuing war against Ukraine.

Trump made the comments Sunday night in a pair of posts on his social media platform Truth Social after Lt. Gen. H.R. McMaster, who served as Trump’s national security adviser during his first administration, criticized the president for “coddling Putin” while putting increased pressure on Ukrainian President Volodymyr Zelenskyy.

“H.R. MCMASTER, A WEAK AND UTTERLY INEFECTIVE LOSER!” Trump wrote.

“We should worry less about Putin and more about the migrant rape groups, drug lords and murderers who are entering our Country,,” he said in a subsequent post.

McMaster had criticised Trump and Vice President JD Vance following their meeting with Zelenskyy at the Oval Office. In a heated exchange, Trump and Vance severely criticized the Ukrainian President before cutting the negotiations short.

McMaster stated on Friday, “It’s impossible to understand how President Trump and Vice-President Vance are determined to exert more pressure on Zelensky when they appear to be coddling Putin- the man who started this horrible war in Ukraine.”

Zelenskyy asked for guarantees of security in light of the ongoing war after Russia invaded Ukraine over three years ago.

Russian leaders and Russian state-run media were jubilant after this testy exchange.

After the exchange with Zelenskyy, several European and other world leaders came to his defense. The Ukrainian President thanked them all on social media for their support.
