WASHINGTON, (Reuters) – Social media platforms such as Facebook (NASDAQ;), Twitter (NYSE:), YouTube (NYSE:), and TikTok need to act quickly in order to reduce the impact of false information – which includes Donald Trump’s Big Lie that his defeat was due fraud – during this year’s U.S. congressional elections. Rights groups stated on Thursday.

After the election of Joe Biden to be President in 2020, social media platforms have retreated from supporting policies to combat electoral disinformation. More than 100 advocacy groups led by Common Cause wrote to executives.

An explosion of disinformation led then to the Jan. 6, 2021 attack at the U.S. Capitol, by Trump supporters. This disinformation, they claimed, was continuing to grow, citing research, and reporting.

Common Cause sent a letter to its chief executives, which was signed by over 100 organizations. It stated that “high-profile disinformation spreadingers and other evil actors continue to use social media platforms for disseminating messages that undermine trust and in elections,”

The candidates were able to use the Big Lie to pre-emptively claim voter fraud and dispute the results in the 2022 election. They wrote, “This is damaging American democracy and undermining trust in the integrity our elections.”

This letter was also sent to CEOs at Google (NASDAQ) and Instagram LLC. Snap Inc (NYSE:), called on the companies to prioritize fact-checking as well as providing access to data in real time to outside researchers and watchdogs.

According to the letter, Trump must not be denied the White House by the “Big Lie” of voter fraud.

These groups demanded transparency regarding political ads, enforcement practices and algorithmic model design.

Some others who signed included voting rights, election integrity groups, the Center for American Progress as well as the League of Women Voters and Greenpeace. They also represented the National Association for the Advancement of Colored People (NAAC) and the Arab American Institute.
