To add to the other comment and give an analogy: say you’re concerned that I secretly possess keys to the back door of your house and I can freely come and go. It’s technically possible. But two questions are important; how come you’ve never seen me in your house or any signs I’ve been there? And secondly, why do me and my friends keep asking you to give us your back door key?

The information inside of the commas can be omitted, it’s just extra detail. The sentence can still read as ‘The Trump administration cut funding to Yale University’s Humanitarian Research Lab last month.’
