The Polish crowd attending President Trump's speech in Warsaw repeatedly interrupted his remarks with chants of "Donald Trump!" and "USA! USA!"
At a wreath-laying ceremony in Krasinski Square, the excited crowd broke out into an American-style, "USA! USA! USA!" chant.
Later, during Trump's prepared remarks, the crowd repeatedly interrupted the speech with a "Donald Trump! Donald Trump!" chant.
"The story of Poland is the story of a people who have never lost hope, who have never been broken and who have never ever forgotten who they are," Trump said in Warsaw, before the crowd began chanting his name.
"Thank you so much, thank you," he replied. "Thank you so much. A great honor."
Trump's speech celebrated the United States' alliance with Poland, and announced the country was purchasing the PATRIOT Air Defense Missile System that the Obama Administration had canceled as a part of his revamped START nuclear treaty.
Trump also thanked Poland for being one of the only NATO members to fully honoring its financial commitment to the Western security alliance.
"That is also why we salute the Polish people for being one of the NATO countries that has actually achieved the benchmark for investment in our common defense," Trump said. "Thank you. Thank you Poland. I must tell you the example you set is truly magnificent and we applaud Poland."
Trump also said the United States remains firmly committed to honoring NATO's Article 5.
"To those who would criticize our tough stance" he's taken with asking NATO members to honor their financial commitments, Trump said, "I would point out that the United States has demonstrated not merely with words but with its actions that we stand firmly behind Article 5, the mutual defense commitment."
