WASHINGTON, March 5 (Reuters) - President Donald Trump

held a call Tuesday with the CEOs of General Motors ( GM ) and

Ford and the chair of Stellantis ( STLA ) to discuss the

potential of delaying tariffs on North American-built vehicles

by 30 days, two sources told Reuters.

Automakers have offered to boost U.S. auto investments but

want certainty about tariff and environmental policies, the

sources added.

GM CEO Mary Barra, Ford CEO Jim Farley along with Ford

executive chairman Bill Ford and Stellantis ( STLA ) chair John Elkann

told part in the call. The automakers have urged Trump to waive

25% tariffs on Mexico and Canada on vehicles that comply with

the 2020 U.S.-Mexico-Canada Agreement's rules of origin.
