In August, Trump complained that "Fox is no longer working for us," and in October he based Fox News's bipartisan vote team, noting online that "they suck."
Trump on Thursday also targeted the press more generally , accuses reporters of unduly chronic blasting the development of the impeachment probe.
"The Republican Party, and I, had a BIG day yesterday regarding the fake impeachment hoax, and yet, when I got home to the White House and watched the news coverage on a lot of TV, you would have no idea they were reports on the same incident, "he wrote. "FAKE & CORRUPT NEWS!"
The president's speech came ahead of planned appearances on Capitol Hill by former staff of National Security Council Fiona Hill and State Department official David Holmes, both of whom are expected to provide damaging testimony about Congress.
In other messages on Thursday, Trump again insisted that his telephone conversation with the President of Ukraine, which is at the heart of the investigation into the proceeding, "was PERFECT" and "did NOT say it was wrong" during talks between the two leaders.
"I never thought in my wildest dreams that my name would in any way be associated with the ugly word, Impeachment!" wrote.
Trump repeatedly rescued House Intelligence President Adam Schiff (D-Calif.) And urged GOP members of Congress to continue arguing on behalf of the White House amid the disputed political battle.
"Keep fighting hard, Republicans, you're dealing with human scum that has taken temporary action and all of the Republican Party's rights from us during the most unfair hearings in American history," he tweeted. "But we are winning big, and they will soon be in our turf."
The president also wrote that "sometime before" the 2020 election he would publish his "economic statement" – claiming that he is "clean" and that the document would show Americans that he is "much richer than people even thought."
Trump claimed last September that he would release a report before Election Day with a comprehensive account of his "financial condition".
Attorneys for the president announced last week that they would take to the Supreme Court a legal dispute with New York prosecutors seeking access to his tax returns. Trump on Friday scared the hunt for his financial records as "not legal" and a continuation of former special adviser Robert Muller's investigative "Witch Hunt".
