At its most basic level, Mr Trump's tweet about the historic nature of the delays in assembling his "full cabinet" is demonstrably false.
As of 8 February, Mr Trump has had six of his 15 cabinet selections confirmed by the Senate, with several more awaiting final Senate approval. While he still has a way to go before his entire team is in place, it's hardly historic at this point.
Bill Clinton didn't have his final spot filled until 11 March. Republican George HW Bush took until 17 March. Barack Obama holds the modern record, as his last pick - Health and Human Services Secretary Kathleen Sebelius - didn't get her Senate vote until 28 April.
Only George W Bush, who like Mr Trump won the presidency without securing a plurality of the popular vote, had his full team in place within weeks of his inauguration, following John Ashcroft's confirmation as attorney general on 30 January.
