Gov. Kathy Hochul treated herself to nearly $1 billion worth of pork-barrel spending in this year’s state budget — allowing her to freely hand out cash as she runs for election against Republican challenger Lee Zeldin. Hochul and her Democratic allies in the Legislature added the $920 million worth of outlays to the $220.5 billion fiscal plan in an 11th-hour move in April that government watchdogs warn is wide open to abuse. “These slush funds are totally unaccountable. It’s not how public dollars should be doled out,” senior policy adviser Rachael Fauss of Reinvent Albany said Friday.
