Trump vows to veto Democrat bills if they win Congress majority

US President Donald Trump has pledged to use his veto power against bills proposed by Democrats if they win a majority in the upcoming congressional midterm elections.

Trump said he could become "Mr. Veto" if Democrats take control, explaining that he would use his presidential authority to reject any legislation they send to him.

The president added that he expects Democrats would realize, after two months of repeated vetoes, that this approach is a waste of time, which would push them to negotiate and reach an agreement.

Trump's remarks come as opinion polls indicate that his declining popularity could boost Democrats’ chances of regaining a majority in at least one chamber of Congress, with the possibility of winning both.
