New York: As the November 3 presidential vote nears, there are fresh signs that the nation's electoral system is again under attack from foreign adversaries.
Intelligence officials confirmed in recent days that foreign actors are actively seeking to compromise the private communications of US political campaigns, candidates and other political targets while working to compromise the nation's election infrastructure.
Foreign entities are also aggressively spreading disinformation intended to sow voter confusion heading into the fall.
There is no evidence that America's enemies have yet succeeded in penetrating campaigns or state election systems, but Democrat Joe Biden's presidential campaign confirmed this week that it has faced multiple related threats.
The former vice president's team was reluctant to reveal specifics for fear of giving adversaries useful intelligence.
Because of such secrecy, at least in part, foreign interference largely remains an afterthought in the 2020 contest, even as Republicans and Democrats alike concede it poses a serious threat that could fundamentally reshape the election at any moment.
Biden's campaign is increasingly concerned that pro-Russian sources have already shared disinformation about Biden's family with President Donald Trump's campaign and his Republican allies on Capitol Hill designed to hurt the Democratic candidate in the days leading up to the election.
When asked directly, the Trump campaign refused to say whether it had accepted materials from any foreign nationals related to Biden.
Trump was impeached last year after being caught pressuring Ukrainian leaders to produce damaging information about work Biden's son did in the region, even though repeated allegations of corruption against the Bidens have been widely discredited.
Wisconsin Senator Ron Johnson, a key Trump ally and chair of the Senate Homeland Security Committee, denied having accepted any damaging materials on Biden from foreign nationals even after at least one Ukrainian national, Oleksandr Onyshchenko, told The Washington Post he had shared tapes and transcripts with Johnson's committee and Trump ally Rudy Giuliani.

House Democrats announced Friday they have subpoenaed Secretary of State Mike Pompeo for documents he turned over to Johnson's panel.
"It does a disservice to our election security efforts when Democrats use the threat of Russian disinformation as a weapon to cast doubt on investigations they don't like," Johnson spokesperson Austin Altenburg said.
The 2020 campaigns and party committees have been receiving regular briefings from the National Counterintelligence and Security Center, whose director, Bill Evanina, released a rare public statement last week confirming Russia's continued work to meddle in the US election.
