WASHINGTON (Reuters) - Republican presidential candidate Donald Trump on Thursday will propose making all interest on car loans fully tax-deductible, according to excerpts of a speech seen by Reuters ahead of remarks in Detroit.

The proposal is the latest in a long string of potential tax cuts the former U.S. president has floated during the final weeks of his campaign against Democratic Vice President Kamala Harris.

Trump will also propose cutting the tax rate on U.S. domestic manufacturers to 15% and said he will bar all autonomous vehicles from Chinese companies from traveling on U.S. roads.

If elected, he will need congressional support to pass changes of tax laws.
