Position was CORKR intersection to directly over SFO [VOR] at approximately 8;000 MSL. Had navigation flag on GNSS from GPS jamming  Was tracking fine up to SFO; Over SFO GNSS made a turn directly to ZZZ or so was thought; however; it was off course; Controller asked what our previous clearance that had been given; which was HOLLR; GRIJO; CORKR; SFO; ZZZ. Original clearance was GPI DIRECT to ZZZ. On the NW side of Nevada; there was GPS jamming was in progress. We reported it; and checked with controllers to see if our course was accurate. They informed us it was; and that if necessary they would give us a heading. Upon changeover to Oakland Center; we advised the Controller that GPS jamming had been in progress; and that we still had a navigation flag. He then issued a clearance to follow the fixes listed above; and we then asked how much longer the GPS jamming would continue. He said a few more miles. we advised him we still had a navigation flag on our GNSS; but apparently he was distracted; and told us to continue without issuing a heading. We were then turned over to another controller who apparently had not been informed of the ongoing issue. Hence once over SFO VOR; was when the issue listed above was encountered. We were not told if there was a near miss; he just gave us a heading to 180 and vectored us to the airport after that. Once on the ground; we were advised to call approach control for a possible deviation. We attempted to call but could not get through to anyone. We advised the Tower we were not able to reach anyone; so he tried to call and failed; but then he got through with another number. They said to disregard; and we then proceeded to ZZZ1 where the flight terminated.
