Stripe made a similar comment, telling the FT that it is "supportive of projects that aim to make online commerce more accessible for people", but will not be moving forward with the Facebook-backed crypto project at this time.
"We appreciate their support for the goals and mission of the Libra project".
As of now, the Libra Association members are facing a lot of pressure from governments and regulators, many of whom find the project threatening to the existing financial system.
Notably, none of these five companies have rejected the possibility of working with the Libra Association in the future.
PayPal was the first of Libra's big partners to leave, announcing last week it would no longer be involved. France and Germany both stated last month that they would attempt to block Libra from operating in Europe, saying it posed risks to European Union states' sovereignty.
Brown said in a statement after the announcements on Friday that the companies had been "wise to avoid legitimizing Facebook's private, global currency".
What do you think about another set of companies leaving Libra?
This time around, Visa, Mastercard, eBay, and Stripe are pulling their support. Initially, there were 28 startups behind Libra's development, although they assured that the number would grow to close to 100 members as the year passed.
The Facebook CEO will be the sole witness at the hearing, which is entitled, "An Examination of Facebook and Its Impact on the Financial Services and Housing Sectors".
Along with the two payment giants, several other large companies have said they're exiting Libra.
The remaining association members, including Lyft and Vodafone, consist mainly of venture capital, telecommunications, blockchain and technology companies, as well as nonprofit groups.
