Donald Trump's latest round of interviews on U.S. news networks has many people wondering what the presumptive Republican nominee is saying here.

In a series of phone interviews Monday morning, Trump said "there's something going on" with President Barack Obama's reaction to the Orlando shooting. 

President Obama said it was a "heartbreaking" day for LGBT communities and a reminder that any attack on Americans is an "attack on all of us."

Obama also used the press conference to talk about gun control.

"It is therefore a further reminder of how easy it is for someone to get their hands on a weapon that lets them shoot people in a school, or in a house of worship, or a movie theatre or in a nightclub," he said. "And we have to decide if that's the kind of country we want to be and to actively do nothing is a decision as well."

Trump reiterated his call for Obama to resign because he did not use the words "radical Islam" in his speech following the Orlando shooting. 

Trump's implication that "there's something going on" with Obama, that he "gets it better than anyone understands," was remarkable to reporters covering the U.S. election. 

Obama's chief speechwriter, Jon Favreau, called Trump's implication "frightening." 

Trump also suggested that Muslims in the U.S. know who is plotting to attack American targets but won't tell authorities. 

Supporters of Trump applauded his focus on Muslims in the U.S. as part of the problem. 

Trump also called for an end to the U.S. accepting refugees from Syria, despite the fact that the shooter, Omar Mateen, was an American citizen born in New York. 

Donald Trump said that if the people in the club had been armed, "you wouldn't have had the tragedy that you had." He talked over CNN journalist Christine Romans, who pointed out that there were armed guards at Pulse. 

Trump insisted that, like Obama, the presumptive Democratic nominee Hillary Clinton refused to use the words "radical Islam" in her response to the shooting. He ignored Romans when she pointed out that Clinton had, in fact, used those very words earlier on CNN.
