Parents of two Americans killed in Benghazi sue Hillary Clinton for wrongful death; should attorney be sanctioned for filing frivolous lawsuit?

NPR is reporting that the parents of two Americans killed in Benghazi, Libya, are suing Hillary Clinton for wrongful death, alleging the 2012 attack "was directly and proximately caused" by the then-secretary of state's mishandling of government secrets.  Even though none of the many Congressional investigations nor the FBI investigation found any proof that the attack was due to access to information in Clinton's emails, the lawsuit argues that Islamic terrorists were able to track the movements of Ambassador Chris Stevens and plot the deadly siege because of Clinton's use of a personal email server to conduct government business.

Here is a copy of the complaint. The main argument is this:

It is highly probable, given Defendant Clinton’s history of reckless handling of classified information, that Defendant Clinton, as Secretary of State, sent and received information about Ambassador Christopher Stevens and thus the U.S. Department of State activities and covert operations that the deceased were a part of in Benghazi, Libya. This information was compromised from the second that it left Defendant Clinton’s private e-mail server and easily found its way to foreign powers including, but not limited to Russia, Iran, China, and North Korea. As a direct result of Defendant Clinton’s reckless handling of this classified, sensitive information, Islamic terrorists were able to obtain the whereabouts of Ambassador Christopher Stevens and thus the U.S. State Department and covert and other government operations in Benghazi, Libya and subsequently orchestrate, plan, and execute the now infamous September 11, 2012 attack.

In the section on "facts" (presumably the factual basis for the complaint), the plaintiffs affirm that "Islamic terrorists obtained the information sent and received by Defendant Clinton about the location of Ambassador Christopher Stevens and thus the U.S. Department of State and the covert CIA and other government operation s in Benghazi and used it to plan, orchestrate, and carry out the horrific and devastating attack on the American diplomatic compound in Benghazi, Libya on September 11, 2012 (“Benghazi Attack”), resulting in the death of four Americans..."

Now, this is a very different type of statement.  This is an affirmative statement of fact, which, presumably, the plaintiffs will be able to prove.  Is there any evidence that what is alleged here is true?   Not according to any of the investigations I have heard of, but I guess it is possible there is information out there I am not aware of.  Are you?  Let me know.

If there is no basis in law or fact for the complaint, this is a frivolous lawsuit, and I think it will be dismissed in due time.  The only question in my mind is whether the lawyer who brought it will be sanctioned for violating the ethical duty, and procedural rules, against bringing frivolous claims.  According to Above the Law, the lawyer "has been banned from multiple judges’ courtrooms" and has orchestrated other politically motivated legal stunts, including a deportation petition against President Obama, which claimed the president was born in Kenya; alleging the Clintons murdered White House associates in the 90s; and filing lawsuits accusing the Clintons of racketeering.
