The lawsuit alleges the congressional candidate failed to pay the firm $200,000. Isaiah Martin, who recently announced his candidacy for the U.S. House of Representatives in Texas’ 18th Congressional District, is now facing a lawsuit filed by Grassroots Analytics, Inc.

Following the passing of U.S. Rep. Sylvester Turner, the race for Texas’ 18th Congressional District is heating up as candidates step forward to fill the seat.

This will be the second time Martin has run for the seat but faces Harris Co. Attorney Christian Menefee, who was endorsed by late Rep. Sheila Jackson Lee's daughter and serves as his campaign's chairwoman.
