WASHINGTON (AP) — The Latest on the presidential campaign (all times local):

11:50 a.m.

Democrat Joe Biden is leading President Donald Trump in the battleground state of Pennsylvania.

By Friday morning, Biden overtook Trump in the number of ballots counted in the state, which Trump must win to have a shot at reelection. Biden leads by more than 9,000 votes. The contest is still too early for The Associated Press to call. Votes in the state are still being counted.

Trump’s lead dwindled after Election Day when state officials began processing mail-in ballots, a form of voting that has skewed heavily in Biden’s favor. Trump spent months claiming — without proof — that voting by mail would lead to widespread voter fraud.

If there is less than a half percentage point difference between Biden’s and Trump’s vote totals, state law dictates that a recount must be held.

By Friday morning, Biden overtook Trump in the number of ballots counted in the state, which Trump must win to have a shot at reelection. Biden now holds a nearly 6,000-vote advantage.

4:40 a.m.

Democrat Joe Biden is now leading President Donald Trump in the battleground state of Georgia.

By Friday morning, Biden overtook Trump in the number of ballots counted in the battleground, a must-win state for Trump that has long been a Republican stronghold. Biden now has a 917-vote advantage.

The contest is still too early for The Associated Press to call. Thousands of ballots are still left to be counted — many in counties where the former vice president was in the lead.

An AP analysis showed that Biden’s vote margins grew as counties processed mail ballots cast in his favor.

There is a potential that the race could go to a recount. Under Georgia law, if the margin between Biden and Trump is under half a percentage point of difference, a recount can be requested.
