Mr Trump failed to attend last week’s debate over his strained relationship with Fox News and Mr Murdoch.
The videos then went on to target president Biden, the Department of Justice, Democrats, Fox News, special prosecutor Jack Smith, and media mogul Rupert Murdoch.
"Crooked Joe Biden is completely controlled by China, Ukraine and various other countries," Mr Trump said, appearing to read from a teleprompter.
He went on to add that the mentioned countries know "everything" about the president along with his misdeeds, which Mr Trump said were "many".
Mr Trump then pivoted to Afghanistan, accusing the president of leaving the conflict-torn country in "shame and defeat".
After sharing a few more videos, Mr Trump paused to wish everyone in Florida dealing with Hurricane Idalia well, before swiftly returning to post more ramblings.
Mr Trump alleged that the country has a "Department of Injustice" that was rigging the election for President Biden. »
