No question he leaked it himself. Petty, vindictive, possibly insane, and all the power of US military and intelligence services available to him? Nobody close enough to him to have access to it would dare.
Also, the 1040 is nearly meaningless without the supporting documentation. The questions are, with what foreign nationals does he do business and in which countries, what companies does he own or invest in that have significant government oversight, contracts, or questionable principals (executives, not ethos, though that could be important as well), are his previous disclosures and claims backed up by his tax returns, things like that.
Really disappointed in both the media and the Republicans for not insisting on full disclosure. People forget in so many ways the guy volunteered to run. Serving as President comes at a high price, and I just don't get why those who could don't make him pay it.
He's going to spend more in a year on bs travel between the NYC nonsense and running away every weekend to Palm Beach (let alone what the kids cost), than the budget of all those agencies EB listed combined. And no, that's not an exaggeration. My tax dollars are flying his ass around instead of paying for things I think govt should be doing and that benefit hundreds of millions of people here and abroad.
Don't even get me started on him doubling the club dues and socializing with the richie riches who pay him PERSONALLY for access. Whoring out the Presidency...
Arggghhh . /rant.
TLDR: Trump paid $38M in taxes in 2005, when all the lefties thought he hadn't paid any taxes.
