The deadlock in the Israeli elections thwarted hopes in Washington to move beyond Netanyahu, despite Trump's continued support.
Neither Netanyahu's bloc nor the opposition secured a majority, which could keep him in power for months.
"There is Netanyahu's fatigue here," said a former senior Trump official, as concerns grow over Netanyahu's influence on the Iran war and US-Israel relations.
Some US officials want to oust Netanyahu's far-right allies, while analysts warn he may attack Iran to stay in power.
