Speaking from the White House just hours after the deadly attack in Orlando, President Obama delivered a message of unity:
But with just seven months left in his presidency, it's likely that any changes to gun laws and a long-term plan for combatting homegrown extremism will fall on the lap of his successor.
Monday morning, presumptive presidential nominees Hillary Clinton and Donald Trump shared their views on homegrown extremism on national television.
For a deeper look at how the presumptive presidential nominees plan to combat terror at home and abroad, Take Two spoke to Julian Zelizer, professor of history and public affairs at Princeton University. Zelizer is also the author of the book, "The Fierce Urgency of Now: Lyndon Johnson, Congress and the Battle for the Great Society."
