In his speech, Donald Trump stressed that relations between America and Israel had never been as good as they are today.
Before the US president's appearance, people gathered for the event, carrying signs reading "We are Jews for Trump" and "Trump" written in Hebrew.
Many of men and several women wore red yarmulkes with "Trump" emblazoned in white that were distributed at the event.
The Trump administration was recently condemned by the Arab League and the United Nations for recognising the Golan Heights as part of Israel.
That caused a lot of different comments and jokes among internet users.
It seems that others didn't like the idea of yarmulkes with "Trump" written on them.
