Robert Zubrin points out (in an article at New Atlantis) that this stated goal has not received any meaningful funding. The New Atlantis article by Robert Zubrin has an updated write up of his Moon Direct program proposal.
The Lunar Orbital Platform-Gateway (formerly known as the Deep Space Gateway) is receiving some money. The gatewate will be a waste.
The gateway is a planned space station that will orbit the Moon, supposedly serving as an outpost for human explorations to the Moon, Mars, and deep space.
NASA says Orion would take its first crew around the Moon by 2023. Vice President Pence has recently stated a goal of putting astronauts on the gateway by the end of 2024.
The lunar gateway idea is silly. There is no need to have a space station circling the Moon in order to go to the Moon or Mars or anywhere else. And there is not much research worth doing in lunar orbit that can't already be done on the International Space Station, in Earth orbit, or with lunar probes and robots.
