SAN FRANCISCO — Fact checking, an essential element in this year's presidential race, is coming to Google News.

A fact-check feature will appear as a tag among Google news search results, alongside established labels for "highly cited," "in-depth" and "opinion." Sites deemed nonpartisan and meeting the criterion of a fact-checking service can apply for the label.

“We’re excited to see the growth of the Fact Check community and to shine a light on its efforts to divine fact from fiction, wisdom from spin,” Google said in a blog post Friday.

No shortage of claims and counter-claims have plagued the veracity of comments on a wide range of issues in the general election pitting Hillary Clinton against Donald Trump. Most major media outlets now routinely run fact-check boxes and some networks, such as CNN, parenthetically insert headlines verifying or challenging a candidate's claims.

Facebook, which holds considerable sway in how Americans receive their news, has yet to employ a fact-checking feature. The social-networking giant recently landed itself in hot water when its algorithm promoted fake news.
