I think you're referring to a speech given by Trump this morning? probably this one:
Speech is from 3 min to 25 min in the above video, so 22 min long
To summarize:
He spoke only a small amount about recent major news and them mostly about the wall.
Talks about incoming administration - appears to have accepted that he has lost and given up challenging results. this is consistent with recent speech and actions. nothing new or different.
25th amendment will not work against me, he says, no chance.
They were a "mob" that stormed the capitol, then talked about law and order.
Speak mostly about the wall says it's a good wall, will work.
He says they have 450 miles of wall - (checking on wikipedia this appears to be correct but wikipedia says "all but about 47 miles being replacement of existing outdated or dilapidated barriers.")
Funnily enough if you look at the video it looks like the wall behind is such a tiny section it doesn't.
even fill the screen behind him? unless that's misleading, maybe it just curves out of sight.
Talks about arresting illegal immigrants with serious crime records, changes in immigration policy he made.
He is very grateful to the people who help secure the US's borders, some of whom are in the small, socially distanced crowd.
Claims that Mexico is suffering with coronavirus and the wall helped USA out coronavirus from coming to USA (just fact checking this on worldometers and the reported death rate per capita is higher in the US both recently and throughout the pandemic so this is probably a false claim unless Mexico is under reporting)
He is not raging or falling into insanity looking at this. He looks quite relaxed and content. Then again, maybe he was just in a good mood at this moment.
