A few months ago, “Morning Joe” hosts Joe Scarborough and Mika Brzezinski were romantically linked together. Fuelling the fire, US Republican presidential candidate Donald Trump took to Twitter to threaten the privacy of the relationship between Scarborough and Brzezinski.

The speculation was first reported by Page Six, as the publication quoted an MSNBC insider who was adamant that the two were already dating. “Everybody at 30 Rock knows they are a couple,” the source said. “They are constantly together… It’ the worst-kept secret in TV.”

The chemistry between Scarborough and Brzezinski is apparently evident on their morning show. However, this chemistry and the possibility of a relationship was further looked into when Brzezinski’s divorce from her husband of 23 years was confirmed. She split from James Hoffer, a WABC Eyewitness News investigative reporter.

A representative of MSNBC confirmed that Brzezinski was indeed divorced from her husband at the time the report came out, but not once confirmed the rumors about a relationship with Scarborough.

Meanwhile, Scarborough divorced his wife of 12 years, Susan Waren, who was previously an aide to Florida Governor Jeb Bush, in 2013.

Earlier this week, Trump reignited these rumours by going on Twitter and threatening he would one day confirm these rumours.

Trump did not end with just one punch, however. He followed the above by calling Brzezinski “neurotic,” and poking fun at the ratings of “Morning Joe,” saying that it is “unwatchable.” Scarborough went on his Twitter account to reply to Trump.

He followed that up by saying Trump’s tweets only helped his show’s ratings.

The feud between Trump and Scarborough began in May, notes The Washington Post, when the host shared he would never vote for the Republican candidate. It was a stark comparison to their relationship earlier on in the election process, when Scarborough and Brzezinski shared they were believers of Trump’s political prospects. And yet, it was Trump who threw the first punch.
