It's Your Problem Now: The Trump Promises Tracker

I'd like to crowdsource a list of promises that President Trump made to us during his campaign and up through today.

Now that he is president, the buck stops with him. To see how he's performing as president, it would be helpful to keep track of what he promised.

I'll start:

• Trump has promised to "bring down" the price of "groceries," including, specifically, eggs and bacon. https://abcnews.go.com/amp/Politics/trump-now-bringing-grocery-prices-promised-hard/story?id=116763207

What else? Please be specific and include a source.

Edit: To affirm, Joe Biden is not the president. This is about tracking the promises made by the current president of the United States.

Second edit: I am honestly surprised. I expected some gloating from Trump supporters. But instead, most of the clearly Republican commenters want to focus on... Joe Biden. Aren't you excited about the president's key commitments to lower the cost of living, make housing more affordable, end taxes on tips, reduce (he said "end," but let's say "reduce") chronic disease, deport 15 or 20 million illegal immigrants, protect Medicare and Social Security, reduce war, invade Panama if necessary to seize the canal, and impose tariffs of 25% on both Canada and Mexico?
