WASHINGTON – The estrangement between President Donald Trump and Fox News just grows and grows.

Trump added impeachment coverage to his list of grievances against his former favorite news network Tuesday, saying at one point in a pair of tweets that Fox is "trying to be so politically correct" by interviewing Democrats such as Sen. Chris Van Hollen of Maryland.

"So, what the hell has happened to @FoxNews," Trump said. "Only I know!"

He blasted current anchor Chris Wallace – whom he has attacked before – and former anchor Shep Smith, who left Fox last year amid catcalls by the president.

The president lumped Fox in with competitors CNN and MSNBC, whose names he mangled in his tweet storm, and predicted their imminent demise while praising the virtues of Twitter.

"Watch, this will be the beginning of the end for Fox, just like the other two which are dying in the ratings," Trump said. "Social Media is great!"

While still praising individual Fox voices such as host Sean Hannity – who will conduct a Super Bowl Sunday interview with the president – Trump has previously criticized the network in general over issues ranging from its political polling to its hiring of Democratic voices.
