Starting at 14:07 in the video is Hoagland's answer to a question about the US Air Force secret orbital test vehicle code-named X-37B (Hoagland gets its designation wrong, calling it XB37.) Completely ignoring the known and documented fact that this test vehicle has never been further than low (~400 km) Earth orbit, and is certainly restricted to that environment, Hoagland announces that its true mission is to conduct reconnaissance on the SEEKRIT manned bases at the poles of the Moon. I'm not kidding — check for yourself.
He goes on to say, in that breathless tone he adopts when he really wants to get the attention of his disciples, that results from the Indian Chandrayaan-1 Moon lander have demonstrated that Lunar atmospheric pressure has increased by a factor of 100 since it was measured by the Apollo 17 ALSEP back in 1972. He doesn't exactly say how he thinks this came about, but the implication is that he thinks this is evidence that someone is living up there and doing some terraforming.
The key bit of information that Hoagland is utterly missing is that the Apollo 17 data was strictly nighttime atmosphere, whereas Chandrayaan-1 performed the first ever measurement of daytime atmospheric composition and pressure. What's more, the Apollo 17 experiment (Lunar Atmospheric Composition Experiment - LACE) ran for several years, whereas the Indian experiment (Chandra's Altitudinal Composition Explorer - CHACE) was attached to the Moon Impact Probe which did a one-time-only suicide dive to the surface lasting 24 minutes.

The precise problem the designers of LACE faced was the very stark difference between daytime and nighttime atmospheric pressure. It would be, in fact, very difficult—perhaps impossible—to design an instrument with the sensitivity range to measure both.They opted for the night measurement because the extreme day temperature (390°K, or nearly 120°C) causes outgassing from not only the instrument itself but all the technology in the immediate vicinity—the other ALSEP experiments, for example, not to mention the Lunar Module Descent Stage itself. Thus this type of measurement would not have been particularly useful. The CHACE experiment, being a quick kamikaze dive, was inherently less vulnerable to contamination.
The CHACE result is certainly interesting, certainly high, although I think not totally outside expected limits. It is emphatically not evidence that anyone is tampering with the Moon's tenuous atmosphere. It's pretty good science, and we can't expect Richard Hoagland or his followers to understand or appreciate that.
