Nope. If Obama supported it, he's against it. If doing away with a regulation will make him or his "friends" money...gone.
I choose your perspective over hal2kilo's. The man is such a simpleton, he goes by "rules-of-thumb". If Obama was black, then nothing he did can be right -- Trump must overturn all of it. Second to that, he doesn't read intelligence briefings -- he doesn't read anything. If any "expert" who had the ear of EPA and others ventures an opinion, Trump will reject it without any thought or ado. In fact, I would think the way to get Trump to do something requires that you "advise him" with condescension especially, to do its opposite. So if you want to hasten impeachment, tell him "Don't shoot the migrants!" It would be collateral damage, and quite simply -- Trump's fault and wrongdoing. One needn't feel guilty for advising the proper thing, if the recipient of the advice is a sociopathic, narcissistic, paranoid, amoral and corrupt figment of his own grandiose imagination.
It would be HIS fault. Then impeach the bastard, put him on trial for war-crimes or mass-murder, and hang the Sumbitch in public so that the Base must see it.
Like Col. Kurz said in "Apocalypse Now" -- "Horror has a face...And you must make a friend of horror. Horror and moral terror are your friends. If they are not then they are enemies to be feared. They are truly enemies.
Go like Col. Kurz, and do it guilt-free!
