Two Political Brothers Missing?

Out of general curosity and to answer a question from one of my kids I have have tried to find up what’s up with Pres. Clinton’s (half) brother Roger. Last information I could find was from a “concert” in North Korea last December. He seems pretty far out of sight for a “celebarity”. Having struck out on that one got me thinking I havent heard about Neil Bush, that paragon of financial character and GW’s Brother. He seems to have slipped uned the radar too. Anyone know what’s up with them?
