Presidential candidate U.S. Sen. Michael Bennet is using his new book to send a message to Senate Majority Leader Mitch McConnell.
The Colorado Democrat has told voters he will send one copy of his new book, titled "Dividing America: How Russia Hacked Social Media and Democracy," to McConnell, a Republican, for every donation his campaign receives.
The effort began Wednesday, and by midday over 1,300 copies were promised to be sent to McConnell on Bennet's website.
Calling Russian interference "graphic and unsettling," Bennet details how the country used social media to influence public opinion. The book is available in digital or print version, and the digital version is free on his website.
"Russia's mission ... was and is to divide Americans," Bennet writes in the book. "They seek to fracture our country along every possible line."
The second-time author notes that Americans had already begun to divide themselves online when Russia stepped in.
"The Russians didn't create the divisions around which their social media audiences were based — they merely revealed and exacerbated them," Bennet writes. "Every American should find this troubling."
Recent attempts to strengthen election security have not made it past the Senate, and McConnell, R-Kentucky, has faced criticism from Democrats for standing against the measures. McConnell and other Republicans have suggested the measures are merely a Democratic attempt to gain political benefit.
"I’m not going to let Democrats and their water carriers in the media use Russia’s attack on our democracy as a Trojan horse for partisan wish list items that would not actually make our elections any safer,” McConnell said in a Wall Street Journal article.
Many other Democratic presidential candidates have come out in favor of bolstering cyber security in response to Russian interference.
Bennet Colorado rival, former Gov. John Hickenlooper, wrote a guest column for NBC News stating that America avoiding the "warning" from Mueller's testimony on Russia will be at "our peril."
"Our enemies cannot be allowed to undermine our democracy without consequence," Hickenlooper wrote. "Through constant engagement and alignment with our allies, we will create a legal framework aimed at preventing cyberthreats from escalating into war."
Kamala Harris, Joe Biden, Elizabeth Warren, Bernie Sanders, Cory Booker Amy Klobuchar and others have made similar statements regarding the need for increased cyber security measures. Warren and Klobuchar have introduced legislation to establish more rules and security measures in election systems, but no recent attempts have made it past the Senate.
