(CNN) As Pittsburgh prepares to bury the victims of what is believed to be the deadliest attack on the Jewish community in US history, the city's mayor said Monday he thinks President Donald Trump should wait to make a visit.

Trump and first lady Melania Trump plan to travel to Pittsburgh on Tuesday, White House press secretary Sarah Sanders said Monday. Ivanka Trump and Jared Kushner will accompany the President and the First Lady, CNN has learned.

They will make the trip three days after a heavily-armed shooter stormed the Tree of Life Synagogue in the city's Squirrel Hill neighborhood during Sabbath services, killing 11 congregants. Six others were injured, including four police officers, authorities said.

They also will make the trip on the day of the first funerals, with burials scheduled to continue through Friday, Mayor William Peduto told CNN's Anderson Cooper. Peduto said he wants the focus to be on families of victims. Law enforcement will be stretched by the funerals and their processions, continuing security at the site of the Saturday shooting and at other Jewish institutions, he said.

"We did try to get the message out to the White House that our priority tomorrow is the first funeral," Peduto said Monday night.
