Reality Check Verdict: Democrats have slow-walked many of Mr Trump's presidential nominations. It has taken longer so far for him to get the majority of his choices confirmed, although part of that is due to the lateness of a few nominations and delays in submitting background-check paperwork. Mr Trump still has months to go, however, before he sets a record for how long it has taken to have all his cabinet positions filled.
Might want to do some fact-checking on your own whenever before you parrot one of Trump's statements since Trump is a pathological liar.
