Yes, Ukraine has stated unequivocally that they knew nothing of any holding back on military aid until a month later. So there was no quid pro quo in the phone call between the US and Ukraine Presidents.
And given previous aid ripoff by corrupt criminals in Ukraine during the Obama years, it was entirely appropriate for the Trump Administration to see what the new President and his administration in Ukraine were planning for getting a grip on their out of control corruption.
