Russian state-backed hackers are targeting U.S. state and local governments in the run-up to November's election, the federal government issues a warning on Thursday.

Pennsylvania Republicans had sought to block the counting of late-arriving ballots, which the state's Supreme Court had approved last month.

Hundreds of thousands of mail-in ballots could be rejected because of small mistakes. Many groups are rushing to help voters "cure" their ballots so they can be counted.

More than 500,000 ballots were rejected in this year's primaries due to mistakes such as mismatched signatures. Voting rights groups are reaching out to affected voters to help them fix those ballots.

The flurry of last-minute legal action comes as more than 5 million people have already cast ballots, causing some confusion over what voters have to do to ensure that their votes count.

Hundreds of lawsuits related to November's election are working their way through the courts. The outcomes will almost certainly help determine the winner of this year's election.

His appeals have unnerved voting rights advocates and election officials, especially in light of incidents around the country that have pitted armed groups from the left and right against each other.

Republicans are recruiting tens of thousands of poll watchers, saying that Democrats are trying to "steal" the election. Democrats and civil rights groups worry it could lead to voter intimidation.

We answer voter questions about this year's election season — from early voting to mail-in or absentee ballots.

Pennsylvania's governor and state legislature — as well as the national political parties and campaigns — have been at odds, leading to election workers doing what they can to help voters keep up.

In a tight Senate race in Maine, opponents of Republican Sen. Susan Collins are focusing on her role in crafting a 2006 law that they say has crippled the U.S. Postal Service's finances.

Other states will begin doing the same over the next few weeks in an election that's expected to break all records in the number of ballots cast early and by mail.

Tens of thousands of ballots have been rejected in key battleground states, where the outcome in November for the presidency and other races could be determined by a small number of votes.

Thousands of mail-in ballots routinely arrive without a postmark or with one that isn't legible. Election officials have to decide whether to count those ballots and under what circumstances.

Some states' election rules say that mail-in ballots count as long as they're postmarked by Election Day. But some arrive without postmarks and that raises questions about whether they should count.

It is not clear why the invitation has not been accepted, but those familiar with the exchange say the delay is unusual, considering that absentee ballots will go in the mail as soon as September.

President Trump has stepped up his assault on both mail-in voting and the U.S. Postal Service. He stated that without additional money to fund both, Democrats will be unable to expand mail-in voting.

Drop boxes have been used in some states for years, and their use is expanding as more voters cast absentee ballots. But the Trump campaign and some Republicans say they're not secure enough.

With concerns about in-person voting or relying on mail-in voting, more election offices are providing secure drop boxes to submit absentee ballots. But the Trump campaign is suing to limit their use.

With about 100 days left before Election Day, election officials warned this week that they need money from the federal government to deal with the pandemic and long-standing cybersecurity threats.
