According to a document titled "Hurricane Harvey Repair Grant Application and Agreement" from the City of Dickinson, in addition to a requirement that the applicant "must adhere to all applicable rules, regulations, and laws, including building codes, safety rules and securing of all required permits," there is also a "verification not to boycott Israel" agreement.
"Verification not to Boycott Israel. By executing this Agreement below, the Applicant verifies that the Applicant: (1) does not boycott Israel; and (2) will not boycott Israel during the term of this Agreement."
Former Congresswoman Cynthia McKinney drew attention to the document on Twitter, writing, "It's true, folks. One has to pledge not to boycott Israel in order to get funding to rebuild your home."
