1.) Legislation. Biden's COVID stimulus plan mostly focused on getting money into a wide swathe of the economy. It did provide $30 billion to help hard-hit mass transit systems get through the pandemic. It also made money available to state and local governments to spend on infrastructure such as water and sewage systems. That can be considered climate change adaptation and should also improve drinking water quality and reduce water pollution.

The Senate voted yesterday to eliminate a Trump rollback of regulations on methane emissions from the oil and gas industry. The House is expected to follow suit.

What is the legal difference between the actions in this "legislation" section and the previous questions about Executive Orders or Foreign Affairs? What is the legal authority for this legislation to be enacted?

2.) Biden has successfully delayed some rollbacks from going into effect, providing more time to undo them. Similarly, Biden has paused the issuance of new oil and gas leases on public lands. How long that pause will last remains to be seen.

What is the legal reason that the administration is able to delay or pause some regulations and administrative processes? Why does it need more time to "undo" some rollbacks from going into effect?

3.) What's next? Biden has already begun the cumbersome administrative process to eliminate Trump's remaining rollbacks, often with the goal of implementing much stronger regulations than Obama.

What must be the status of the remaining Trump administration rollbacks that necessitate the "cumbersome administrative process"? Describe the basic steps of the administrative process for reversing the remaining Trump administration's regulatory rollbacks. Why is it "cumbersome"?
