This is an inexplicable move. Scratch the surface on Mulvaney's crowded resume and you'll find an ineffective lawmaker who "failed up" to the OMB, where he engineered the largest deficit ever during a period of economic growth. That was grounds for promotion in the Trump regime, so Mulvaney aquired the dubious distinction of being the worst WH COS in history.
It's the news media's job to inform the American public and provide them with diverse viewpoints. Mulvaney is perfectly well qualified to offer informed opinions on topics like Joe Biden's proposed buget. But for the "woke" left, working for Trump disqualifies him?
Savvy media executives know that the run-up to the midterms is the time to retool for the next presidential election. Like it or not, Trump is still a top contender for the GOP nomination in 2024, and CBS will need Trump allies on their roster to ensure access to the top players in that campaign.
