A Twitter hashtag about presidential candidate Elizabeth Warren that started trending in the US after she sparred with rival Bernie Sanders during the Democratic primary debate on Tuesday prompted some users to speculate that Russian bots could be fueling a spike in these tweets. 

Twitter said Wednesday that it looked at whether bots were amplifying the #NeverWarren hashtag but found no evidence that is the case. The social network bars misleading, deceptive and spammy behavior along with attempts to manipulate what's trending. 

Foreign interference in elections have been a growing concern for social media companies including Twitter and Facebook following the 2016 US presidential election. These companies discovered that Russian trolls were using their platforms to sow discord among Americans. Since then, they've been beefing up efforts to crack down on accounts that misled the public about their identity and purpose. In 2018, Twitter released more than 10 million tweets tied to potential disinformation campaigns by Russian and Iranian trolls. 

At one point on Wednesday, #NeverWarren was in the top three Twitter trends in the US, The Hill reported. It started trending after Warren and Sanders disagreed during the debate about whether Sanders said during a private dinner in 2018 that he didn't believe a woman could win the presidency.

Some Twitter users started to wonder if Russian trolls and bots were amplifying this hashtag. 

"I'm calling BS on the authenticity of #NeverWarren..," wrote anonymous Twitter user @NunesAlt on Wednesday. "Have we really learned nothing from 2016?"

The Twitter user, citing, pointed out that tweets with #NeverWarren started to rise at 5 a.m. EST when Americans would be asleep. At 9 a.m. EST, there were an estimated 8,100 tweets per hour with #NeverWarren, according to the site

Other Twitter users echoed the same skepticism about why the hashtag was trending. 

A hashtag starts trending on Twitter if it's being talked about more than it has previously. The list of trends is generated by an algorithm, according to Twitter. The social network, though, said that the conversations were driven by real people, including users who disagreed with its anti-Warren message. Using technology and human review, the company said it proactively tries to identify accounts that are attempting to manipulate conversations on the site. 

Other news outlets, including NBC reporter Ben Collins, pointed out on Twitter that the top tweets about the hashtag were from users who denounced using it. By 3 p.m. ET on Wednesday, Twitter users tweeted #NeverWarren 62,000 times, according to NBC. 

As of late Wednesday afternoon, #NeverWarren was longer one of top five trends in the US on the Twitter. Instead, the #NeverTrump had made its way on the list.
