THE STAGE IS SET — Hillary Clinton and Donald Trump will face off tonight in the highly anticipated first debate at Hofstra University. But will they talk cyber? Moderator Lester Holt of NBC News will devote two of the debate's six 15-minute segments to the topic of "Securing America," and national security discussions tend to include at least glancing cybersecurity references.

Both candidates have pledged more aggressive responses to cyberattacks and enhancing the nation's digital shields.

There have been serious concerns voiced by political operatives and former cybersecurity officials about a report in Yahoo News that Mr. Trump’s foreign-policy adviser Carter Page met with aides to Russian President Vladimir Putin.

There has been talk of invoking the Logan Act—a 1799 law that criminalizes private negotiations with foreign governments engaged in "disputes or controversies with the United States." However, no one has ever been prosecuted under that act. Indicting Mr. Page under the Logan Act would require proof that his meetings featured actual negotiations, promises or enticements.

"The use of it would almost certainly draw First Amendment challenges," Ed McAndrew, a former Justice Department cybercrime specialist and current partner at Ballard Spahr, told MC.
