A day after picking up the endorsement of the Buffalo News, Brown will be endorsed Monday morning by Congressman Brian Higgins and State Senator Tim Kennedy.
A recent poll showed Brown with a substantial lead over Bernie Tolbert, his opponent in the September 10 Democratic Primary.
Tolbert, the former FBI agent, has earned notable endorsements from the Police Benevolent Association and the Challenger.
The Primary winner faces Republican Sergio Rodriguez in the November election.
In choosing Brown over Tolbert for its endorsement, the Buffalo News called both candidates "competent men," but Brown has "produced a strong record-even if some of it is not his own doing."
The Higgins endorsement serves to reconfirm the strong connection between the Buffalo Democrats. The focus on their relationship was highlighted during President Obama's recent visit to Western New York when he incorrectly identified Higgins as Buffalo's Mayor.
