None of congress gets secret service protection. They are protected by
the US Capitol Police.
You don't throw good money after bad.
so they are protected by capitol police when they are outside of the capital?
She has the money to buy security.
We shouldn't have to pay for it.
But Trump's enormous extended family being protected by secret service have the money for their own protection too???
So I'm not so certain your excuse of ''having the money, to pay for it'' really works...
Though, Maxine has chosen to be more ''vocal'' than most people in Congress, and should have been aware in this visceral climate, it could bring danger to her....
and even before the death threats came, if I were her, I would have increased my own security the minute President Trump first decided to be the petty and vengeful person that he is,
and started to focus on her in all of his rallies, and with his tweets of his vindictive yet juvenile comments against Maxine Waters, Maxine Waters and Maxine Waters.... he made her a Trump World boogeyman....
And he had (manipulated) his following to spread the hatred towards her, (along with the Russian Trolls)

on the internet...
and let's not forget the Fox News's of Trump's inner circle and Townhalls, Briebarts, Drudges, Gateway Pundits, Truepundits, zerohedges, RT, Sputnik, DailyCallers and Infowars of the Right wing propaganda media circle of friends....and facebook and other social medias...
--------------------------
so, under normal circumstance, I would say Maxine should have prepared for some increased security for herself when off the Hill....
BUT BECAUSE the President chose to retaliate, only a thousand times harder....as the sitting President with his BULLY PULPIT and following, and his decision to bring his followers in to his vengeful and vindictive fight against Maxine Waters.....
the Secret service probably should cover her....
IF the president had been a decent man, and simply kept his mouth shut...
instead of constantly pushing his followers in to HATING HER like he has done, then I would say no, she could cover her own security.
no one would even know who Maxine Waters is, but the people who voted for her....if it were not for right wing media and Trump
