In the wake of the 2016 election, the social media giant was forced to suspend Twitter for nearly six months after a number of users tweeted about their experiences using the platform.
Twitter said it was doing so to ensure that “social media is not used as a tool to promote divisive political viewpoints”.
It was not immediately clear how the suspension affected the political activity of the accounts.
“This suspension will be temporary and will allow us to work on improving the tools and processes that govern the use of Twitter,” the company said in a statement.
The company also said that it would continue to monitor for content that might encourage “disparaging or harassing behaviour” against people and groups on the platform, but did not say how it planned to do so.
Twitter did not immediately respond to a request for comment.
