DAVID MUIR: We turn now to the race for the White House. President Biden in his home state of Pennsylvania again tonight, a state he'll need to win this November. Biden aiming to draw the contrast between him and Donald Trump, who has spent much of this week in court. Here's Mary Bruce.
MARY BRUCE: Tonight, fully aware that Donald Trump's attention is focused on his criminal trial in New York, President Biden lasering in on battleground Pennsylvania. Speaking to steelworkers, Biden touting his work on the economy and taking swipes at his opponent.
JOE BIDEN: 492,000 new jobs so far in Pennsylvania alone. Under my predecessor, who's busy right now, Pennsylvania lost 275,000 jobs. I mean, let's look at the facts. On my watch, unemployment hasn't been this low or this long in 50 years.
BRUCE: Biden's leaning into his working class roots on a three-day swing through this must-win state. Meeting construction workers in Pittsburgh, visiting his childhood home in Scranton, where he told voters he understands them in a way Trump never will.
BIDEN: Donald Trump looks at the world differently than you and me. He wakes up in the morning in Mar-a-Lago thinking about himself.
BRUCE: The president, well aware that the polls are tightening and that he is gaining ground, has spent more time in Pennsylvania than any other battleground. By our count, visiting the state more than 30 times since taking office. David.
MUIR: Mary Bruce, who was in Pennsylvania, now back in Washington for us. Mary, thank you.
