Keep aside that Trump is asking. This is not a US-only problem, it's a worlwide issue. Reporting every 3 months apart from taking large resources and slow down of decision making, the worst issue is that companies want to always show quarter-on-quarter increases in profits - and that's killer. Results in twisting facts, layoffs, selling assets etc, just to keep showing higher numbers. It is like saying are we getting closer to our destination every 15 minutes while driving from the east coast to west coast of the US. It is non-sense to expect continous driving - as we would break for meals, rest, refuelling etc. Likewise, companies need time to grow and there will be periods in the year when numbers will fluctuate. It is indeed a badly needed correction to the business environment to do away with quarterly reporting . I would say, do it only yearly.
