US ambassador cuts diplomatic ties with Polish parliament speaker over Trump comments

The US ambassador to Poland has cut off all diplomatic contact with the speaker of the Polish parliament. This happened after the speaker, Szymon Hołownia, made comments criticizing Trump and saying he should not receive a Nobel Peace Prize, which the US ambassador called 'insulting' and 'despicable'.

The Polish Prime Minister, Donald Tusk, then had a heated exchange with the US ambassador, telling him not to 'lecture' Poland about its internal political discussions. The dispute centers on whether a US diplomat should sever ties with a foreign official over criticism of a US presidential candidate.
