It appears that "Steve" posted a video online possibly outlining his plan and intentions.
Check it out here:
The video, posted to YouTube Tuesday afternoon, shows a man that looks like the climber talking about why he planned to climb Trump Tower.
While ABC News has not confirmed that the man in the video is the climber, a high ranking police source tells us there is "no reason to believe it's not him."
Police tell ABC News that the video is being investigated.
