GEOFF BENNETT: It's only been a week since# the 2024 race for the White House was upended, but it's already entering the final countdown,# now fewer than 100 days until Election Day.

In the last couple of days, the Republican# ticket -- that's Donald Trump and J.D.

Vance --# hit the campaign trail together, while# Vice President Kamala Harris spent her first full weekend as the# likely Democratic nominee.

KAMALA HARRIS, Vice President of the United States# (D) and U.S. Presidential Candidate: Because## we have a lot to talk about.

LISA DESJARDINS: Tonight, Vice President# Kamala Harris' campaign is basking .. the glow of a colossal fund-raising# haul and a new surge in the polls.

Her campaign announced yesterday that it## had raised over $200 million in# the first week of her candidacy.

That's more than the Trump campaign# raised in the entire month of June.

And team Harris got a boost in manpower,# saying more than 170,000 volunteers signed up.

But, even with that, at a Massachusetts## fund-raiser this weekend, Harris# warned against overconfidence.

KAMALA HARRIS: We're the underdogs of this## race.

But this is a people power# campaign.

And we have momentum.

LISA DESJARDINS: Those signs of energy# are also showing up in the polls.

A new ABC News/Ipsos poll shows voters warming# up to Harris fast, with 43 percent favorability.

That number was 35 percent just a week ago.

The jump was especially# pronounced among independents,## now with 44 percent viewing Harris favorably.

That's up by 16 points.

GOV.

ANDY BESHEAR (D-KY): Are you ready## to elect Kamala Harris president#.. LISA DESJARDINS: Stumping for Harris on the trail# this weekend, a number of high-profile surrogates who are also among her potential running mate.

The V.P.

could pick her V.P.

as soon as this week.

LISA DESJARDINS: The blitz of events and# messaging, including what the campaign dubbed a weekend of action, include# a new angle of attack against opponents Donald Trump and J.D.

Vance.

GOV.

TIM WALZ (D-MN): But we're# not afraid of weird people.

GOV.

TIM WALZ: We're a little bit# creeped out, but we're not afraid.

KAMALA HARRIS: Donald Trump has been# resorting to some wild lies about my record, and some of what he and his running mate# are saying, well, it's just plain weird.

LISA DESJARDINS: But team Trump# is also hitting the trail hard,## with Trump holding three major# appearances since Friday, starting with the former president and his number two appearing together in Minnesota.

That's a state that hasn't voted for a# Republican for president in over 50 years.

But Trump wants to redraw the map, even# as he himself writes new attack lines.

U.S. Presidential Candidate:# We have a brand-new victim.

And, honestly, she's a radical left lunatic.

And# she has no clue.

She has no clue.

She's evil.

LISA DESJARDINS: Since the attempt on his life,## Trump has only had events at indoor# venues, including this one in Minn..

But he has vowed to return# to Butler, Pennsylvania,## where the shooting happened,# for a rally at a later date.

And, today, the FBI said the# former president has agreed to## be interviewed as part of their# investigation into the shooting.

But over the weekend, many Trump# allies also had to explain these## comments Trump made to a gathering# of Christian conservatives on Friday: DONALD TRUMP: Christians, get# out and vote just this time.

DONALD TRUMP: You won't have to do it anymore.

Four more years, you know what?# It'll be fixed.

It'll be fine.

You won't have to vote anymore, my beautiful# Christians.

I love you, Christians.

LISA DESJARDINS: A spokesman said Trump# was talking about uniting the country.

Running mate J.D.

Vance# gave an explanation Sunday.

SEN. J.D.

VANCE (R-OH), Vice Presidential# Candidate: So I think he's saying,## get out there, make sure this election# matters, because, .. the next four years, we may# not have a real election if## the Democrats give illegal# aliens the right to vote.

LISA DESJARDINS: Harris and# Trump will both campaign in## battleground states in the next few days.

And with just 99 days left in# the race, every day counts.
