A Twitter statement yesterday said the social media company shared data with congressional investigators about ads from RT, a television group with links to the Moscow government.
Twitter said RT spent USD 274,000 in 2016 on Twitter ads that may have been used to try to influence the US election.
The news comes after Facebook acknowledged foreign entities linked to Russia paid to promote political messages on the leading social network, potentially violating US election laws.
"This is an ongoing process and we will continue to collaborate with investigators," the statement said.

Twitter said it examined efforts by foreign agents to interfere with the election after Facebook indicated it found 450 accounts that appeared to have been used for this purpose.
"Of the roughly 450 accounts that Facebook recently shared as a part of their review, we concluded that 22 had corresponding accounts on Twitter," the statement said.
The statement added that RT, which was named in January in a US intelligence report on election interference, spent at least USD 274,100 in 2016 for 1,823 tweet ads or "promotions" that "definitely or potentially targeted the US market."
"These campaigns were directed at followers of mainstream media and primarily promoted RT Tweets regarding news stories," the statement added.
"We are concerned about violations of our terms of service and US law with respect to interference in the exercise of voting rights," the statement said.
Twitter said some of the ads, or promoted tweets, aimed to deceive voters by telling them they could "text to vote," which has no basis in fact.
"We have not found accounts associated with this activity to have obvious Russian origin, but some of the accounts appear to have been automated," the statement said.
"We have shared examples of the content of these removed tweets with congressional investigators."
Democratic Senator Mark Warner called Twitter's presentation "deeply disappointing" and "inadequate."
Warner told reporters that the Twitter data was "basically derivative based on accounts that Facebook had identified (and) showed an enormous lack of understanding from the Twitter team of how serious this issue is, the threat it poses to democratic institutions, and again begs many more questions.
