The Senate Intelligence Committee Chairman Richard Burr said the Committee was seeking to understand the technical aspects of identifying foreign influence on the platforms, and what regulations would be needed to ensure that foreign entities do not intrude US elections, the Hill reported.

Previously Facebook revealed that Russia-linked ads had been bought on the platform in an effort to influence the elections.

Facebook released information on the measures it used to “defend the integrity” of the German elections last weekend, after reports of foreign interference during the US and French presidential elections. These included removing “tens of thousands” of fake accounts, and featuring Related Articles, in an effort to “help voters understand the parties’ policy positions”.

Meanwhile Facebook CEO Mark Zuckerberg responded to President Trump calling Facebook “anti-Trump”. Zuckerberg stressed Facebook’s neutral stance,  calling Facebook a “platform for all ideas”, and saying that “both sides are upset about ideas and content they don’t like”. He also highlighted Facebook’s efforts to support the democratic process, but said he regretted his now-infamous comment about Facebook potentially having changed the outcome of the US elections, which he called “pretty crazy idea”.
