Trump's strategy is to immediately counterattack when attacked, and to not let his opponents get a second wind. This is no different.
Trump should point out, relentlessly, how Mitt Romney trashed him when he viewed it expedient to do so, and sucked up to him in other circumstances when it seemed expedient to do so. This says more about Mitt Romney than it does about Trump. Romney called Trump a "con man" and a "carnival barker" in early 2016, but after the 2016 election, he had lamb chops with Trump in a pricey restaurant and pretty much begged to be Secretary of State. Somehow, Mitt Romney isn't winning me over on his "character" arguments.
So what, so many politicians in the past join cabinets of Presidents they disagree with . If Kerry won in 2004 and he wanted to interview John McCain for the the Sec of State position , McCain would take it even though he and other Republicans called Kerry’s foreign policy dangerous and cutting and running in the campaign.
The fact is Trump broke the law Fuzzy and even right wing legal experts like Judge Napolitano have said so and Napolitano is no where near a liberal . He went after Obama hard for 8 years and harder than many many other Fox Pundits do as well .
Then let impeachment happen. But let the entire House vote to authorize the inquiry.
