Donald Trump called out the United States' "dysfunctional" immigration system, vowing to temporarily suspend immigration from some countries if he is elected president. 

Speaking on the Orlando terror attack in New Hampshire, Trump noted that the terrorist's family came to the U.S. from Afghanistan and that his father supported the Taliban regime. 

"When I'm elected, I will suspend immigration from areas of the world where there’s a proven history of terrorism against the United States, Europe or our allies until we fully understand how to end these threats," said Trump, adding that the country "has no choice" but to take this action.

He noted that "the immigration laws ... give the president powers to suspend entry into the country of any class of persons."

Trump said after a security assessment is completed, there will be a new system that "serves the interests and values of America."

He said that many people are now admitting he was right for calling for the temporary immigration ban in December following the San Bernardino attack.

The GOP's presumptive nominee said President Obama does not know what he's doing and has "failed" the United States. 

Trump faulted Obama for failing to call out "radical Islamic terrorism," adding that Hillary Clinton "broadcasts weakness" to the world by using the same language.

Watch his remarks above.
