WASHINGTON, Jan 15 (Reuters) - President-elect Donald

Trump's nominee to head the U.S. Transportation Department said

Wednesday electric vehicles should pay to use roads.

Most revenue for federally-funded road repairs is collected

through taxes on diesel and gasoline, which EVs do not pay.

"They should pay for use of our roads. How to do that, I think,

is a little more challenging," said Sean Duffy, a former

Republican lawmaker at his confirmation hearing before the

Senate Commerce Committee.
