Lockheed Martin [LMT] has announced it will also join several other defense firms in pausing political contributions to lawmakers in the wake of the Jan. 6 attack on the U.S. Capitol.

The company now joins

Northrop Grumman [NOC], Raytheon [RTN], BAE Systems, Leidos [LDOS] and Boeing [BA] in suspending donations, for the time being, for all members of Congress, not just the 147 lawmakers who voted against certifying the results of Joe Biden’s presidential victory.

“Lockheed Martin routinely evaluates and updates our political action committee contribution strategy to reflect our core values and the constantly changing political landscape and priorities. As we enter a new political cycle, we are not making political contributions as we continue this evaluation to ensure our political donation and engagement program remains aligned with our business priorities,” the company wrote in a statement Wednesday evening. 

The company is a major contributor to political campaigns, donating nearly $6.3 million during the latest election cycle, according to the Center for Responsive Politics’ OpenSecrets.org.

Lockheed Martin was also one of the top 20 PAC donors to members who voted against certifying election results, contributing $651,000 to those campaigns during the 2020 election.
