President Donald Trump has pledged to advocate for the release of jailed Hong Kong media tycoon Jimmy Lai, whose national security trial resumed this week amid judicial skepticism over sedition charges.

A Hong Kong court heard final arguments Monday in the landmark national security trial of former pro-democracy newspaper founder Jimmy Lai, who could be sentenced to up to life in prison if convicted.

Hong Kong media mogul Jimmy Lai's lawyer clashed with judges on Thursday over whether the pro-democracy newspaper founder's "armchair punditry" on social media and other platforms breached the city's national security law.
