Republican presidential candidate Donald Trump's campaign will launch a $10 million advertising blitz in six battleground states this week as it tries to counter a surge of voter enthusiasm and donations for his Democratic rival Kamala Harris.
It is Trump's biggest ad buy since January, when he was fighting off Republican rivals for the party's nomination. Trump's campaign did not respond to requests for comment, but the blitz comes as Harris’ candidacy has changed the race.

Since President Joe Biden dropped out last week and endorsed Harris, she has rapidly consolidated support within the Democratic Party and from big-money donors. She has also sparked a newfound energy among groups such as young voters that Biden had been struggling to win over.
