Not a single piece of significant legislation has passed. Trump has issued various Executive Orders and that's all. The so-called " Repeal and Replace Obamacare" was a series of bungling by Senate majority leader " Just Say No" McConnell as he tried various reuse to get the votes necessary. They all failed, from Repeal and Replace to just Repeal to "skinny? Repeal. Members got earfuls from constituents and Trump went on a rampage of tweeting blaming everyone but himself. They will try again but after 7+ years of promising to Repeal and Replace, the Affordable Care Act is still standing ( many who voted for Trump really got to see what was in store for the if that happened as the Congressional Budget Office came out with its findings that would see 26+ million lose coverage from preconditions to Medicare and Medicaid and the billions in tax cuts for the " wealthy 1%).
Various attempts to ban Muslims from some countries ( Libya, Syria etc.), were struck by from Hawaii to Washington and this is in limbo also. The Wall is still not funded and is going no where. The NATO issue is still in murky waters. Trump went to Europe and got no respect ( at one stage he was sitting by himself, while others were meeting and at the photo-op, he was relegated to the second row.). Then he went to the G-20 meeting and was soundly criticized for having a meeting with Putin, where no American translator was present. Then he was invited by Pres. Macron to the Bastille Day celebration and there was a whole lot of hand holding, backslapping and "praise" for Macron's wife " you are in good shape" ( Macron has since lost 10% in the polls, the Theresa May syndrome of hand holding). NATO remains unresolved.
The Russia probe has been a millstone around Trump's neck. It is not going away and has ensnared his son JR., his son-in law Kushner, his former campaign manager Manafort and others still to come. The special prosecutor, Mueller and the Asst. AG. have come under attacks from Trump, with threats of firings but so far nothing has been done, except training his sights on Attorney General Sessions. He has been vicious and unrelenting in his attacks on Sessions but so far Sessions has held his ground . He blames Sessions for recusing himself from the Russia probe, this before there was a Russia probe, saying that Sessions ( Sessions was a Trump loyalist from day 1 and was the first Senator to endorse him ) should have told him that he would recuse himself. Sean Spicer his Press Secretary could not take the "beating" that he was getting at press briefings, trying to explain Trump and defending and earned his disfavor ( which Trump, true to form, showed in a very crude way, by not inviting Spicer to meet with the Pope.
Now he has appointed the vile and vulgar Scaramucci to be his Communications Director and all hell has broken loose as he has gone on an expletive ridden rant attacking "leakers", and picking a fight with Chief of Staff Priebus.
Trump has announced a ban on transgender in the military, because of medical costs. In 2014 it cost $84 million for erectile dysfunction. It may cost about $2.4 to 8.4 million for transition-related health care. Another broken promise. Even Sen. Hatch, a Mormon came out against Trump's proposal and the military is in confusion, about what to do with those serving ( they volunteered, unlike the 5-time draft-dodger Trump.
The turmoil has turned into a tornado of accusations and nothing gets done.
