While speaking to reporters on the South Lawn, Trump was asked if he had a message for Poland on the anniversary of the Nazi invasion that took place on Sept. 1, 1939.

“Mr. President, do you have a message for Poland on the 80th anniversary of the Second World War?“ a reporter asked.

“I do have a great message for Poland,” Trump responded. “And we have Mike Pence Michael (Mike) Richard PenceFormer Pence aide: White House staffers discussed Trump refusing to leave office Pence vows for law and order everywhere Trump met with chants of protest as he pays respects to Ruth Bader Ginsburg MORE, our vice president, is just about landing right now. And he is representing me."

"I look forward to being there soon. But I just want to congratulate Poland,” he continued. “It’s a great country with great people. We also have many Polish people in our country; it could be 8 million. We love our Polish friends. And I will be there soon.”

The day is more a day of remembrance in Poland than a day of celebration. German President Frank-Walter Steinmeier marked the occasion by asking Poland for forgiveness for his nation's aggression.

"This was a German war crime," Steinmeier said at a ceremony also attended by Pence.

Trump had been scheduled to visit Poland on Saturday and Sunday to attend ceremonies commemorating the anniversary in Warsaw. He canceled the trip on Thursday, however, due to Hurricane Dorian, which is expected to hit the United States.

Pence, who visited Poland in Trump’s place over the weekend, offered more somber remarks than the president in an address from Pilsudski Square on Sunday, The Washington Post reported.

“It is difficult for any of us who are not Poles to fathom the horrors that began here 80 years ago, on this day, the first of September 1939,” the vice president said.

“While the hearts of every American are with our fellow citizens in the path of a massive storm, today we remember how the gathering storm of the 20th century broke into warfare and invasion followed by the unspeakable hardship and heroism shown by the Polish people,” he continued.

He also called out the “twisted ideologies of Nazism and Communism” in his remarks, as well as the “unspeakable evil of the Holocaust,” which he noted, “systemically murdered more than 3 million of Poland’s Jewish citizens.”
