Good morning,
Either I have got a number of clues wrong or it makes no sense
7d - Me? I’m an eccentric with energy (5) M x I x x
12a - Very large cases catch returning court specialist (5) S x x x O
26a - Trump’s huge following behind one put down (5) x x M x E
28a - Garden intruder was angry about empty warehouse (7) R x x x N x D,
I have looked at RAGWEED, but the N from 16d Anchorman kills this.
