Given ICE’s mission, an endorsement of Trump would suggest the agency officially agrees with the candidate’s public remarks regarding immigration. However, federal employees are prohibited from influencing political elections on behalf of their agencies under the Hatch Act of 1939.
The act forbids public, agency-sponsored endorsements or oppositions, as well as employees’ engagement in partisan activity in the workplace, including displaying campaign paraphernalia before Election Day.
However unions are free to endorse.
“The Hatch Act does not restrict the ability of employee organizations to engage in political activity” if they do not violate the act’s other provisions, CRS states. “For example, fundraising activity (otherwise restricted for employees generally) is permitted in the context of federal labor organizations.”
According to CRS, the provision states that “employees who are members of a union that has a political action committee (PAC) may solicit, accept, or receive contributions from other members of that union if the donor is not a subordinate and the contribution is made to the union’s PAC,” as long as the activity does not take place while the employees are at work.
