First lady Melania Trump said Thursday that all people should be allowed to "live their lives without fear."

"As many of you know, a main focus of my husband's presidency is safety and security of the American people. I think us all of us can agree people should be able to live their lives without fear, no matter what country they live in. That is my wish for all of us around the world," Melania Trump said in her introduction of President Trump before his speech in Warsaw's Krasinski Square.

The first couple earlier laid wreaths and paid tribute to Poland's history under the Nazi regime. Melania Trump thanked the "generous hospitality" of Polish President Andrzej Duda and his wife, Agata Kornhauser-Duda.

She also remarked that her visit to the Copernicus Science Centre earlier in the day was very informative. She said the science center inspires people to "observe, experiment, ask questions, and seek answers."

Melania Trump, who is accompanying her husband on his Europe trip, thanked the Polish people for the warm welcome to their "very special country."
