US President Donald Trump has thrown his support behind another embattled far-right European leader, backing Marine Le Pen after French presidential hopeful was convicted of embezzlement and barred from political office.

WASHINGTON (Reuters) - U.S. President Donald Trump offered support to French far-right leader Marine Le Pen on Thursday after a Paris court earlier this week convicted her and two dozen figures from her National Rally (RN) party of embezzling European Union funds.

Far-right party chief Jordan Bardella called on the French to rally this weekend to protest against a ruling that banned Marine Le Pen from running for public office for five years after being found guilty of embezzling European Union funds.
