Russia is supporting Donald Trump, China is supporting Joe Biden and Iran is looking to plant turmoil in the US presidential election, a top intelligence official has cautioned in a sobering evaluation of foreign interfering.

The announcement on Friday by William Evanina, director of the National Counterintelligence and Security Center, raises fears of a repeat of the 2016 election when Russia controlled social media to help Trump and hurt his adversary Hillary Clinton.

“Russia is using a range of measures to primarily denigrate former Vice President Biden and what it sees as an anti-Russia ‘establishment’,” Evanina said. “This is consistent with Moscow’s public criticism of him when he was Vice President for his role in the Obama Administration’s policies on Ukraine and its support for the anti-Putin opposition inside Russia.”

Evanina recognized Andriy Derkach, a pro-Russia Ukrainian politician, as “spreading claims about corruption – including through publicized leaked phone calls” to assault Biden’s campaign. The Washington Post announced that Derkach has met repeatedly with Trump’s personal lawyer, Rudy Giuliani, who has pushed conspiracy theories about the previous VP.

Evanina additionally cautioned that some “Kremlin-linked actors” were spreading bogus cases about defilement to undermine Biden, while others were attempting to “boost President Trump’s candidacy via social media and Russian television”.

Evanina, the top intelligence official monitoring dangers to the election, is a Trump deputy. His announcement records China before Russia however presents less explicit proof of direct impedance by Beijing.

“We assess that China prefers that President Trump – whom Beijing sees as unpredictable – does not win re-election,” Evanina said. “China has been expanding its influence efforts ahead of November 2020 to shape the policy environment in the United States, pressure political figures it views as opposed to China’s interests, and deflect and counter criticism of China.”

He added: “Beijing recognizes that all of these efforts might affect the presidential race.”

Evanina featured China’s analysis of Trump’s treatment of the coronavirus pandemic, the conclusion of China’s office in Houston and the White House reactions to Chinese activities in Hong Kong and the South China Sea. On Friday, the US forced authorizes on Hong Kong’s CEO, Carrie Lam, and 10 other senior authorities. Trump has likewise requested crackdowns on the Chinese proprietors of the famous applications TikTok and WeChat.

Iran, in the interim, was trying to undermine US democratic institutions and Trump, and to isolate the nation in front of the 2020 races, Evanina’s announcement said.

“Iran’s efforts along these lines probably will focus on on-line influence, such as spreading disinformation on social media and recirculating anti-US content. Tehran’s motivation to conduct such activities is, in part, driven by a perception that President Trump’s reelection would result in a continuation of US pressure on Iran in an effort to foment regime change.”

Trump pulled the US out of an nuclear arrangement concurred by Barack Obama and forced different assents on Tehran.

The anti-Trump pressure group National Security Action denied that China’s public activities rose to the level of Russia’s covert election obstruction. “Jarringly, the statement attempted to minimize what Russia is doing – again attacking our democracy in a bid to secure Trump’s reelection – by comparing it to China’s public criticism of the administration’s recent punitive measures against Beijing,” a spokesperson, Ned Price, said. “Any interference in our democracy is unacceptable, but there is no equivalence between the two efforts.”

In a press conference at his golf club in Bedminster, New Jersey, on Friday evening, Trump responded to the appraisal by demanding: “I think that the last person Russia wants to see in office is Donald Trump because nobody’s been tougher on Russia than I have, ever.

“China would love us to have an election where Donald Trump lost to ‘Sleepy’ Joe Biden. They would own our country. If Joe Biden was president, China would own our country … Iran would love to see me not be president.”

The president added: “I’ll make this statement. If and when we win, we will make deals with Iran very quickly. We’ll make deals with North Korea very quickly. Whatever happened to the war in North Korea? You haven’t seen that, have you?”

A hacking and social media campaign by Russia in 2016 is credited by US intelligence with helping Trump to triumph. It triggered the special counsel Robert Mueller’s examination, which depicted Russian meddling however didn’t infer that there had been direct collusion by Trump or his campaign.

The November election is as of now under siege from the coronavirus pandemic, worries about whether the system can deal with a surge in mail-in voting and steady assaults by Trump on the respectability of the procedure.

Evanina cautioned that foreign enemies may attempt to interfere with election systems by attempting to sabotage the voting procedure, taking election information or questioning the validity of results: “Foreign efforts to influence or interfere with our elections are a direct threat to the fabric of our democracy.”

The report raised worry on Capitol Hill. Marco Rubio and Mark Warner, the top Republican and Democrat on the Senate intelligence committee, said they “encourage political leaders on all sides to refrain from weaponizing intelligence matters for political gain”.

Mitch McConnell, the Republican Senate greater part pioneer, stated: “It is no surprise our adversaries have preferences in our elections. Foreign nations have tried to influence our politics throughout American history. As Director Evanina’s statement makes clear, Russian malign influence efforts remain a significant threat. But it would be a serious mistake to ignore the growing threats posed by China and Iran.”
