"I think it's important for us, we the people, to express First Amendment rights and say we want to see them".
People began to reach out nearly immediately, asking if they could lend a hand.
"I'm just a law professor who sent out a tweet", said Taub, who teaches at Vermont Law School. "I wrote 140, or less, characters".
Of course, turnout at the tax marches could surprise on the upside.
The objective is to put pressure on President Donald Trump to release his tax returns, which he has not yet done, explaining his taxes are now under IRS audit.
The demonstrations, organized by a loose coalition of labor and left-leaning groups with various economic agendas, are meant to focus on Trump's refusal to disclose his tax-paying history, something his predecessors in the White House have done for more than 40 years. So Trump critics are prepared to make some noise. "We're making it fun and peaceful and family friendly", Brar said.

The organizers said more than 180 marches are planned throughout 48 states in addition to the march in D.C.
Trump has cited an audit as the reason he won't release his taxes.
There is no law requiring presidents to release their tax returns, but Mr Trump has found himself under public pressure and some information from a 2005 tax return was leaked to the media last month.
He said it's necessary to see "how President Trump gets his money and keeps his money" as those are "national security issues ... that should be open to the public".
The public is up roaring at the governmental agencies that have been ignoring this nationwide demand and various political movements, including bipartisan politicians, are participating in the large scale demonstrations on Saturday to express their mistrust and disbelief in the Trump administration. "Our democracy can not function with this kind of secrecy. And when we look at the Republican plan, it's clear they are putting corporations and the wealthy ahead of the middle class. Americans don't want that".
Kathleen Petersen, a retiree who is organizing the march in Cheyenne, Wyoming, also helped organize the local Women's March there the day after Trump was inaugurated. But Trump's taxes - which a House panel has already voted along party lines against requesting - could be a tougher nut to crack. Maxine Waters, D-Calif., and Jamie Raskin, D-Md., are scheduled to speak at the march in Washington.

And then there is the Trump chicken.
Organizers were initially hesitant about embracing the inflatable fowl, but as Taub recalled, "Somebody on our executive committee said, 'Well, you can't really have a blow-up balloon of the US Constitution'".
