The parents of two Americans killed in attacks in Benghazi, Libya, say in a lawsuit that Hillary Clinton is responsible for the deaths of their children.

The wrongful death lawsuit against Clinton was filed Monday in federal court in Washington, DC. Clinton was secretary of state at the time of the Sept. 11, 2012, attacks.

The plaintiffs are Pat Smith of San Diego and Charles Woods of Portland, Oregon. State Department employee Sean Smith and security contractor Tyrone Woods were among four Americans killed in the attacks.

The suit says Clinton’s “negligent and reckless” use of a private e-mail server compromised the Americans’ security. House Republicans blamed the Obama administration for loose security, but not Clinton personally.

Attorney Larry Klayman is representing the parents. Klayman is a longtime Clinton critic.

Donald Trump says his plan for the U.S. economy will produce annual growth of at least 4 percent, a figure not seen since the final year of Bill Clinton’s presidency.

The Republican nominee says that the proposal he unveiled Monday to cut taxes and create jobs makes a 4 percent growth rate “easily attainable and I think even more than that.” He was interviewed Tuesday on Fox News’ “Fox and Friends.”

Democratic rival Hillary Clinton has dismissed Trump’s plan as offering “super big tax breaks” to huge companies and rich people.

The economy’s average annual growth rate since the last recession ended in June 2009 is just over 2 percent, the slowest since the 1930s.

Donald Trump is seeking to quell concerns he lacks the discipline or policy know-how to make a competent president, even as the list of fellow Republicans deeming him unfit for the Oval Office grows.

Maine Sen. Susan Collins is the latest Republican to announce her intent not to vote for her party’s nominee. Collins said late Monday she’d thought “long and hard” about whether she was obligated to support the GOP nominee and decided she could not.

She says she’s become “increasingly dismayed by his constant stream of cruel comments” and his inability to apologize.

The defection from a respected senator adds to a chorus of GOP voices insisting they can’t back Trump. It comes as Trump is trying to shift attention to his revamped plan for far-reaching tax cuts.
