During the first gathering of the American Technology Council, Apple CEO Tim Cook, Amazon CEO Jeff Bezos and venture capitalist and noted Trump backer Peter Thiel will be among those in attendance.

The council, formed by the White House Office of American Innovation (which is in turn helmed by White House Senior Adviser and Trump’s son-in-law Jared Kushner), has been tasked with modernizing government technology while also tackling the increasingly pertinent issue of cybersecurity.

The 17 tech elites, who are expected to meet with Trump, Kushner, and other officials throughout the day, will certainly have much to talk about. Some of those on the invite list have publicly spoken out against at least some of the commander in chief’s decisions in the past. Microsoft CEO Satya Nadella has voiced his concerns over Trump’s decision to exit the Paris Agreement on climate change, while others, like Cook, have opposed Trump’s stance on immigration.

The full list of CEOs and other tech leaders meeting with Trump includes:

• Ajay Banga, CEO of MasterCard
• Jeff Bezos, CEO of Amazon
• Zachary Bookman, CEO of OpenGov
• Safra Catz, Co-Chief Executive of Oracle
• Tim Cook, CEO of Apple
• John Doerr, Chairman of Kleiner Perkins
• Pat Gelsinger, CEO of VMware
• Alex Karp, CEO of Palantir
• Brian Krzanich, CEO of Intel
• Tom Leighton, CEO of Akamai
• Bill McDermott, CEO of SAP
• Steven Mollenkopf, CEO of Qualcomm
• Satya Nadella, CEO of Microsoft
• Shantanu Narayen, CEO of Adobe
• Ginni Rometty, CEO of IBM
• Eric Schmidt, Executive Chairman of Alphabet
• Julie Sweet, CEO of Accenture
• Peter Thiel, Founders Fund

Notably absent from the list are Uber CEO Travis Kalanick, currently on leave from his company, Tesla and SpaceX CEO Elon Musk, who previously stepped down from Trump’s economic advisory after the Paris decision, and Salesforce CEO Marc Benioff, who could not be there due to scheduling conflicts, according to The Wall Street Journal.
