WASHINGTON (REUTERS) - Swedish climate activist Greta Thunberg will testify on Thursday (April 22) to a United States congressional hearing on fossil fuel subsidies, which the committee's progressive chairman is pressuring President Joe Biden to end.

Ms Thunberg will appear virtually before the House Oversight Committee's subcommittee on the environment the same day Mr Biden kicks off a virtual two-day Earth Day summit with world leaders, seeking to assert US leadership internationally on climate change.
