Under-fire NSW trade minister Stuart Ayres says he should have told his former colleague John Barilaro not to apply for a US job that has engulfed the government in crisis.
Premier Dominic Perrottet is under mounting pressure to sack the deputy Liberal Party leader amid the seven-week scandal over how Mr Barilaro landed the $500,000-a-year trade role he created when he was a minister.
Documents released to a parliamentary committee probing the controversial appointment have raised serious questions over the recruitment process.
