Pat Smith drew some of the most intense crowd reactions at the Quicken Loans arena in Cleveland on the opening night of the Republican National Convention with her sharp criticism of former Secretary of State Hillary Clinton.

Smith's son Sean was one of four men who lost their lives in the attack in Benghazi on September 11, 2012.

"The last time I talked to Sean, the night before the terrorist attack, he told me, 'Mom, I am going to die," Smith said in her opening remarks, as the delegates and other attendees sat quietly listening to her painful tale. "All security had been pulled from the embassy, he explained, and when he asked why, he never received a response. Nobody listened. Nobody seemed to care."

But as Smith began to criticize Clinton, members of the crowd began cheering her on with outbursts.

"For all of this loss, for all of this grief, for all of the cynicism the tragedy in Benghazi has wrought upon America, I blame Hillary Clinton," she said to cheers. "I blame Hillary Clinton personally for the death of my son."

When a crowd member yelled up at her, Smith responded, "She lied to me and then called me a liar."

Smith has criticized Clinton in the past, even saying there's a "a special place in hell" for people like her during a TV interview in March.

But the convention stage and the viewers watching on TV and online at home may have been her biggest audience yet.

"Donald Trump is everything Hillary Clinton is not," Smith said to another round of cheers, describing him as blunt, direct and strong.

A long-awaited inquiry into a deadly militant attack on the US mission in the Libyan city of Benghazi late on December 18, 2012 slammed State Department security arrangements there as 'grossly inadequate.' But the months-long probe also found there had been 'no immediate, specific' intelligence of a threat against the mission, which was overrun on September 11 by dozens of heavily armed militants who killed four Americans.

"If Hillary Clinton can't give us the truth, why should we give her the presidency?"

Smith was one of just many who planned to take aim at Clinton on night one of the convention, themed "Make America Safe Again."
