5 things for September 28: Tax overhaul, Puerto Rico, Facebook, Equifax, Hefner

(CNN) Politics and football may be mixing it up these days, but Peyton Manning says he's most definitely not running for the Senate. Here's what else you need to know to Get Up to Speed and Out the Door. (You can also get "5 Things You Need to Know Today" delivered to your inbox daily. Sign up here.)

1. Tax overhaul

President Trump pulled the wraps off his long-awaited tax overhaul plan. It's a mix of massive tax cuts and a serious simplification of the tax code that he called a "once-in-a-generation opportunity." So, what's in it? It would collapse the number of personal income tax brackets from seven to three. It would double the standard deduction for married and single filers. And it would slash the corporate tax rate to 20% and dump the estate tax.

Now comes the hard part: getting this thing through Congress. Republicans know it will be a heavy lift, and Dems are billing it as a giveaway to Trump's rich friends. The ambitious effort also comes on the heels of the Senate's latest failure to repeal and replace Obamacare (though Trump now says he may take on the issue by executive order), as well as controversies over wealthy Trump Cabinet members living high on the taxpayer dime.

2. Puerto Rico

The effort to get aid to hurricane-ravaged Puerto Rico is being stymied by an almost 100-year-old law. The Jones Act requires all goods ferried between US ports to be carried on ships built, owned and operated by Americans. But now, it's making it really expensive to ship stuff from the mainland to the island territory. There have been calls to suspend the act so aid can get to Puerto Rico faster, but so far, the President has only said he's thinking about waiving the rule, which was suspended after Hurricanes Harvey and Irma.

A week after Hurricane Maria, Puerto Ricans are still desperate for help, and experts say a medical crisis is looming. Relatives here on the mainland are still trying to learn the fate of their loved ones, and a volunteer network of ham radio operators is making critical communications on the island possible. Celebrities, including the rapper Pitbull and Marc Anthony and Jennifer Lopez, are pitching in to help, and Trump's inaugural committee has donated $3 million to relief efforts. Here's how you can support survivors, too.

3. Facebook

At least one of the Facebook ads bought by Russians during the 2016 presidential campaign referenced Black Lives Matter and was specifically targeted to reach audiences in Ferguson, Missouri, and in Baltimore, sources with knowledge of the ads told CNN.

Ferguson and Baltimore had gained widespread attention for the large and violent protests over police shootings of black men. The decision to target the ad in those two cities offers the first look at how accounts linked to the Russian government-affiliated troll farm known as the Internet Research Agency used geographically targeted advertising to sow political chaos in the United States, the sources said.

4. Equifax

To say Equifax hasn't handled its massive data breach very well is being generous. First, the credit-reporting agency didn't immediately inform the world that the personal information of as many as 143 million people had been compromised. Then, it took flak for charging fees to folks who wanted to protect themselves by initiating a credit freeze. But now, Equifax may finally be doing something right: It will soon offer a program that'll let consumers lock and unlock their credit files for free -- for life.

5. Hugh Hefner

Hugh Hefner, the Playboy founder who built an empire on magazine centerfolds and sexual fantasies, has died at age 91. Hefner started Playboy in the '50s, and its success helped spur the sexual revolution. During its heyday in the 1970s, the Playboy empire included TV shows, clubs (with waitresses in those iconic bunny ears) and a jazz festival. Hef, as he liked to be called, also had critics, who dismissed him as a relic of a more sexist era. Still, tributes have poured in, including from Gene Simmons of Kiss and the Rev. Jesse Jackson.
