CNN’s Jake Tapper took a dig at press secretary Sean Spicer on Saturday by making reference to one of the more controversial aspects of President Trump‘s political history.

Earlier today, the New York Times put out a report about Trump’s continued feud with the press, his past relationship with tabloids, and his frustration with leaks in his administration. Even though co-writer Glenn Thrush says he emailed Spicer to ask about certain details of the Times‘s story ahead of time, Spicer took issue with a certain aspect of the content:

For the record @nytimes @grynbaum can’t even get where I was born right and failed to ask https://t.co/hIb3QFxK6P — Sean Spicer (@seanspicer) February 25, 2017

Enter Tapper, who added this bit of snark to the conversation:

I imagine it must be really annoying when someone puts out false info about where you were born. Must really bother you!! cc @BarackObama https://t.co/BCQAWiEksB — Jake Tapper (@jaketapper) February 25, 2017

Tapper, of course, is referencing the “birther” conspiracy theory that Trump propagated for years before he became president; he suggested that Barack Obama was not a natural-born American citizen (and therefore not a legitimate president), and he flirted with the idea for years before finally renouncing it during the 2016 election.

UPDATE – 7:35 p.m. EST: The Times has offered a correction on their part:

This “correction” is the perfect kicker to excellent @GlennThrush & @grynbaum story on Trump and the press. https://t.co/2abUbEyjNN pic.twitter.com/tc1SaR6KLP — Harry Siegel (@harrysiegel) February 25, 2017
