Yahoo Finance says it accidentally tweeted out a racial epithet when promoting a story about the cost of President-elect Donald Trump’s plans to increase the size of the U.S. Navy.

The headline for the story on Yahoo Finance is, “Trump Wants a Much Bigger Navy: Here’s How Much It’ll Cost.” But when it was tweeted Thursday, the word “bigger” had an “n” as its first letter instead of a “b.”

The tweet was deleted and Yahoo Finance tweeted an apology , chalking it up to a spelling error. A company spokeswoman referred to the statement when asked for further comment.
