(CNN) President Donald Trump said Saturday that the outcome of the deadly shooting at a Pittsburgh synagogue would have been different had an armed guard been in place.

"If there was an armed guard inside the temple, they would have been able to stop him," he said to reporters before boarding a flight to a pair of events later in the afternoon.

Eleven people were killed and six injured in Saturday morning's shooting at the Tree of Life synagogue in Pittsburgh. Pennsylvania man Robert Bowers , 46, of suburban Baldwin, faces 29 charges in connection to the rampage.

Trump also said the nation should strengthen its laws surrounding the death penalty.

"When people do this, they should get the death penalty," he said. "Anybody that does a thing like this to innocent people that are in temple or in church ... they should be suffering the ultimate price, they should pay the ultimate price."

When asked if the shooting indicated a need to revisit gun laws, Trump replied that the shooting "has little to do with it" and that an armed guard might have been able to stop the gunman "immediately."

Asked if he was advocating for armed guards inside of places of worship, Trump replied, "no, it's certainly an option."

Michael Eisenberg, the immediate past president of Tree of Life Congregation Synagogue, told CNN affiliate WPXI that on the high holidays, there is a police presence. But not on this Saturday.

"On a day like today, the door is open," he said. "It's a religious service, you could walk in and out."

Trump praised law enforcement officials for doing "an incredible job" and said he had spoken with Pennsylvania Gov. Tom Wolf and Pittsburgh Mayor Bill Peduto.

Upon landing in Indianapolis to speak at an agriculture convention, Trump said the shooting appeared to have anti-Semitic motivations.

"It looks definitely like it's an anti-Semitic crime, and that is something you wouldn't believe could still be going on," Trump said.

The FBI is the lead agency on the investigation and is treating the shooting as a hate crime, according to Pittsburgh Public Safety Director Wendell Hissrich.

'Pure evil'

During remarks at the Future Farmers of America convention in Indianapolis, Trump again called the act "anti-Semitic" and condemned it as "pure evil."

"This wicked act of mass murder is pure evil -- hard to believe, and frankly something that is unimaginable," he said.

"This was an anti-Semitic act," the President added. "You wouldn't think this would be possible in this day and age, but we just don't seem to learn from the past."

"There must be no tolerance for anti-Semitism in America or for any form of religious or racial hatred or prejudice," Trump added.

Trump said ahead of a political rally in Illinois later Saturday that he planned to visit Pittsburgh, although he did not say when the trip would occur.

At the rally itself, Trump again denounced anti-Semitism and repeated his call for the use of the death penalty.

"They have to pay the ultimate price," Trump said. "They can't do this."

He went on to deliver remarks largely characteristic of his rallies, talking in particular about the economy and immigration while attacking Democrats as he sought to motivate Republicans in the midterm elections.

'Ultimate price'

Vice President Mike Pence echoed Trump's remarks on the shooting, telling rallygoers in Las Vegas, Nevada, that "anyone who does such a thing in a temple or a church should pay the ultimate price."

"As Las Vegas knows all too well, what happened in Pittsburgh today was not just criminal, it was evil," Pence said, alluding to the October 2017 shooting at a Las Vegas country music festival, where 58 people were killed and hundreds more wounded.

"There is no place in America for violence or anti-Semitism, and this evil must end," he added, calling the shooting "an attack on innocent Americans and an assault on our freedom of religion."

Presidential adviser and first daughter Ivanka Trump, who along with her husband Jared Kushner is Jewish, said Saturday that "America is stronger than the acts of a depraved bigot and anti-semite."
