A war of words has erupted between two Fox News hosts after Tucker Carlson (left) mocked his colleague Shepard Smith (right) over comments on the issue of President Donald Trump and his Ukraine call. Carlson targeted Smith during his show on Wednesday night after the latter had defended a Fox News analyst earlier in the day.  The ongoing saga was ignited on Tuesday when Smith had Fox News contributor and former judge Andrew Napolitano on his show regarding the Trump-Ukraine call.
