This unbelievably moronic “Malthus connection” between Lee and John Holdren seems to be spreading like a contagious disease.
The nuts are plainly unaware that practically anyone with an interest in population theory will have quoted Malthus at one time or another. They are behaving exactly as though Malthus is some mutual friend or perhaps supporter and mentor of both Lee and Holdren.

It’s worth noting that Marx, Engels, and Lenin all condemned Malthus:

Engels called Malthus’s hypothesis “…the crudest, most barbarous theory that ever existed, a system of despair which struck down all those beautiful phrases about love thy neighbour and world citizenship.” Engels also predicted[citation needed] that science would solve the problem of an adequate food supply.

In the Marxist tradition, Lenin sharply criticized Malthusian theory and its neo-Malthusian version, calling it a “reactionary doctrine” and “an attempt on the part of bourgeois ideologists to exonerate capitalism and to prove the inevitability of privation and misery for the working class under any social system”.
