In addition to legislation mentioned above, on April 11, 2013, Jeffries introduced the
Prison Ship Martyrs' Monument Preservation Act (H.R. 1501; 113th Congress). The bill would direct the
Secretary of the Interior to study the suitability and feasibility of designating the
Prison Ship Martyrs' Monument in
Fort Greene Park in
Brooklyn as a unit of the National Park System (NPS).
[58] Jeffries said, "as one of America's largest revolutionary war burial sites and in tribute to the patriots that lost their lives fighting for our nation's independence, this monument deserves to be considered as a unit of the National Park Service."
[59] On April 28, 2014, the Prison Ship Martyrs's Monument Preservation Act was passed by the House.

On July 15, 2014, Jeffries, who in private practice addressed intellectual property issues, introduced the
To establish the Law School Clinic Certification Program of the United States Patent and Trademark Office (H.R. 5108; 113th Congress), which would establish the Law School Clinic Certification Program of the
United States Patent and Trademark Office (USPTO) to be available to accredited
law schools for the ten-year period after enactment of the Act.

In 2015, Jeffries led the effort to pass The Slain Officer Family Support Act,
[62] which extended the tax deadline for people making donations to organizations supporting the families of deceased NYPD Detectives Wenjian Liu and Rafael Ramos. The families of the officers, who had been killed in their patrol car on December 20, 2014, in the Bedford-Stuyvesant section of Jeffries's district, had been the recipients of charitable fundraising.
[63] Before the law's enactment, people would have had to make those contributions by December 31, 2014, to qualify for a tax deduction in connection with taxes filed in 2015. With the change, contributions made until April 15, 2015, were deductible. President Obama signed the bill into law on April 1, 2015.

So his accomplishment is a Monument Act, a law school clinic, and extending the tax deadline for donations to organizations supporting two police officers murdered by BLM brownshirts...well I appreciate the last one.
