Donald Trump is set to end a days-long absence from the campaign trail Thursday with a news conference, his first public appearance since rival Kamala Harris named her running mate and embarked on a tour of US battleground states.
Harris has taken almost no questions from reporters since entering the race for the White House on July 21, and Trump is seeking to turn her lack of media exposure into an election issue as she surges ahead in polling and draws blockbuster crowds.
