The family of Eric Garner, the Staten Island man who died while in police custody met with federal officials asking them to investigate.
Garner's family was joined by Al Sharpton in Downtown Brooklyn to meet with U.S. Attorney Loretta Lynch, asking her to call for a federal investigation.
The case is currently under investigation by Staten Island District Attorney Dan Donovan.
Garner died on July 17 after police put him in a chokehold for allegedly selling loose cigarettes.
Sharpton said following the meeting that Lynch was open to the request, but that she did not make any promises.
"She was very open, asked some questions of the family and said she understood, but quite naturally, said she wasn't going to give a direct answer at this time," Sharpton said.
Lynch said she would get back to the Garner family.
The meeting comes just two days before a march is set to take place on Staten Island to draw attention to the case.
"Five weeks later, the outrage has not subsided. We expect three to five thousand people minimum there. We've not had that large a march on this case, so if it is the thinking of some, that if they wait us out that it would dissipate—they will see that it has grown in terms of the outrage," Sharpton.
"We're marching to get justice for my husband and I would like all y'all to come out and march, if you want. But we need a lot of marchers to march and get justice for my husband," said Eric Garner's widow, Esa w Garner.
The Staten Island Chamber of Commerce is advising businesses on the march route to take precautions on Saturday. Some are planning to close down.
Sharpton said it sounded like an effort to stoke the fire, and emphasized that the marchers are not anti-police, but rather against police who break the law.
