President Trump is putting together a proposal for a second round of tax cuts to fortify his reelection platform, but the effort is coming together only hesitatingly and faces uncertain buy-in even among Republicans.

“It will be a very substantial tax cut for middle income folks who work so hard,” Trump said Thursday of his plans to create a middle-class tax cut, speaking during a retreat for House Republicans in Baltimore. He added that the tax cut would be “very, very inspirational” but did not mention any further details.
