Ajit Pai, the Republican chairman of the Federal Communications Commission, will deliver a speech on Friday marking 100 days of him leading the regulatory agency.

Pai will give the speech at the American Enterprise Institute, a conservative think tank.

The FCC chair made waves last week with his announcement that he would begin proceedings this month to roll back the agency’s net neutrality rules, which were passed in 2015 and require internet service providers to treat all web traffic equally.

Pai argues that the rules went too far by reclassifying internet service providers as telecommunications services, which makes the industry subject to tougher regulations from the FCC.

Net neutrality supporters have argued that getting rid of the rules would allow companies such as Comcast, Verizon and AT&T to create fast and slow lanes on the internet, and even block certain content.
