"The survival of America depends upon our ability to elect Republicans at every level - starting with the midterms next year", Trump said.
Former president Donald Trump listens as his daughter-in-law Lara Trump speaks at the Republican Convention Saturday 5 June, 2021, in Greenville, North Carolina.
Out of office and off social media, Mr Trump now fires out a stream of incendiary statements by email - supporting chosen Republican candidates, launching vitriolic attacks on perceived enemies and relishing the role of king-maker when meeting with allies and party leaders. Republicans have won North Carolina in 11 of the last 13 presidential elections.
When asked by CNBC about the "broader efforts" the "From the Desk of Donald J Trump" blog was a part of, adviser Jason Miller simply said: "Hoping to have more information on the broader efforts soon, but I do not have a precise awareness of timing".
North Carolina had been a strong Republican fort for the Republicans.
On Friday, Trump said that Facebook's decision to ban him for two years from its social media platform was an insult to more than 75 million Americans who voted for him and the tech giant would not get away with acts of censoring and silencing.
Banished from social networks but no less influential among the party faithful, Mr Trump has remained politically active since he left the White House in January.
Trump focused his early remarks on President Joe Biden, which he called "the most radical left-wing administration in history". The claims have triggered a wave of Republican-backed voting restrictions in state legislatures across the country, even though Trump's cries of voting fraud have been refuted by dozens of judges, Republican governors and senior officials from his own administration.
