  We show that there is a sequence of explicit multilinear polynomials
$P_n(x_1,\ldots,x_n)\in \mathbb{R}[x_1,\ldots,x_n]$ with non-negative
coefficients that lies in monotone VNP such that any monotone algebraic circuit
for $P_n$ must have size $\exp(\Omega(n)).$ This builds on (and strengthens) a
result of Yehudayoff (2018) who showed a lower bound of
$\exp(\tilde{\Omega}(\sqrt{n})).$
