The video was posted by the official White House — it appears in the White House video library and was streamed on the White House YouTube channel.
It is presented as an official White House remark/event (hosted on whitehouse.gov and the White House YouTube channel), not a campaign upload.
According to the White House description, “Trump Accounts” refers to a new government program of savings/investment accounts for children (part of the administration’s Invest America/One Big Beautiful Bill initiative), not social-media or private financial accounts.
The White House posted the video; it does not include a full transcript on the video page. Closed captions on the YouTube stream may be available after processing; an official text/transcript was not posted to the White House video page at time of publication.
No policy changes, legal actions, or binding official decisions are listed on the White House video page; the page frames the remarks as a program launch/announcement (Trump Accounts/Invest America) rather than a new executive order or legal filing.
Media outlets and some allied livestream channels covered the remarks (YouTube live streams, RSBN and DVIDS carried the event); mainstream White House media distribution was via the White House site and its YouTube/Facebook pages. I found no major press releases by other agencies immediately summarizing new policy beyond the White House’s own materials.
