Donald Trump is expected to launch dozens of television ads to boost Republicans in key races across the country, with the former US president asserting his political influence as the campaigns head into the final stretch of the midterm elections, according to sources familiar with the matter.

The spots - funded through a newly and specially created political action committee christened Maga Inc, an abbreviation for the Make America Great Again slogan - are anticipated to come in several waves of messaging over the coming weeks, the sources said.
