U.S. President Donald Trump was "apoplectic" with Boris Johnson during a phone call to discuss the British prime minister's decision to allow Chinese firm Huawei a role in Britain's 5G mobile phone network, the Financial Times reported on Thursday.Citing unnamed officials in London and Washington, the FT said the president was livid during the exchange last week after Johnson's government said Huawei could have a limited role in building Britain's 5G mobile network, despite warnings from the Trump administration.The paper said one individual who was briefed on the contents of the call on Jan. 28 said Trump was “apoplectic”. It cited another who said the call was "very difficult" and Trump's tone had taken aback British officials.
