In a dizzying tweet on Wednesday evening, President Trump appeared to threaten to not debate “Radical Left Democrats” or appear on CNN or MSNBC for debates during the 2020 election.

The tweet was in response to news that the Democratic National Committee won’t partner with Fox News for 2020 primary debates. The DNC announced the decision on Wednesday, citing a New Yorker story that dropped this week, alleging that Fox News killed stories not favorable to Trump during the 2016 election.

“Good, then I think I’ll do the same thing with the Fake News Networks and the Radical Left Democrats,” he tweeted. It’s unclear what exactly he means.
