Currently, the US Embassy in Israel is located in the city of Tel Aviv but that could change in the future.
Today President Trump will recognize Jerusalem as the Israeli capital.
Although the government of Israel already considers Jerusalem to be its capital city, that claim is not recognized by the international community, because Palestinians also claim Jerusalem as their capital.
President Trump has previously said he intends to move the US Embassy to Jerusalem, but it's expected he will announce a delay in those plans for now.
President Trump gives a statement on Jerusalem at 12 p.m. Wednesday.
