The 35-year-old businesswoman and Trump adviser, who converted to Judaism before marrying a grandson of Holocaust survivors, laid flowers with the message "From the United States" at the monument dedicated to the victims of the 1943 Warsaw Ghetto Uprising.
Friday and Saturday he'll participate in the G-20 summit in Germany, including a formal bilateral meeting Friday with Russian President Vladimir Putin, but first he's making a stop in Poland.
Warsaw is seeking to raise its defense potential amid Russia's heightened military activity, some of it near Poland's air space.
Trump managed to berate both North Korea and CNN at the same time during a news conference alongside Polish President Andrzej Duda.

A senior adviser to Duda said on Wednesday that PGNiG was in talks over more US gas imports.
Former President Barack Obama, Trump said, drew a "red line" in Syria, a reference to his 2012 remark that the use of chemical weapons by Bashar al-Assad would change his calculus with regard to the conflict there. Notably left out: Chinese President Xi Jinping, whom Trump earlier had enlisted in a campaign to rein in the regime of Kim Jung Un.
"I'm counting on that after negotiations, that I know are already in progress, that long term contract for the import of liquefied natural gas from the U.S. to our port in Swinoujscie, will be signed". Poland will not renew its contract with Gazprom to import gas once it expires in 2022. It's part of Merkel's plan to to fight global warming by reducing her country's reliance on coal and nuclear power.
Trump stressed that he was proud the region was benefiting from U.S. energy supplies.
