Hillary Clinton: Trump Is ‘Unfit and Totally Unqualified’ to Be President Today, Clinton launched one of her sharpest broadsides yet against Trump.

 -- Hillary Clinton slammed Donald Trump’s approach to national security, arguing the country needs “leadership, common sense and concrete plans” after Sunday's massacre in Florida.

Clinton, speaking in Pittsburgh today, launched one of her sharpest broadsides yet against the presumptive Republican nominee, whom she labeled as “temperamentally unfit and totally unqualified to be commander in chief.”

“He has to distract us from the fact he has nothing substantive to say,” Clinton said, referring to Trump’s national security speech in New Hampshire. “We don’t need conspiracy theories and pathological self-congratulations. We need leadership, common sense and concrete plans because we are facing a brutal enemy.”

Clinton said she read “every word” of Trump’s speech and concluded it was full of “lies.”

“He said I’ll abolish the Second Amendment. Well that’s wrong. He said I’ll let a flood of refugees into our country without any screening. That’s also wrong,” Clinton fired off.

Following the shooting in Orlando, which left 49 people dead, Trump tweeted: “Appreciate the congrats for being right on radical Islamic terrorism, I don't want congrats, I want toughness & vigilance. We must be smart!”

Clinton used her remarks to blast Trump's proposal to ban Muslim immigrants from entering the United States, calling it an attempt to “demonize and declare war on an entire religion.”

“He is fixated on the words radical Islam,” Clinton said. “Now, I must say I find this strange. Is Donald Trump suggesting that there are magic words that once uttered will stop terrorists from coming after us?”

She also rebuked Trump's insinuation that President Obama was connected to the Orlando shooting.

Clinton posed this question to Republicans: “Will responsible Republican leaders stand up to their presumptive nominee? Or will they stand by his accusation about our president?”
