In the wake of last week’s violence at the U.S. Capitol, exchange companies, Nasdaq and CME Group, are suspending political donations.

The board of Nasdaq’s political action committee (PAC) announced it “will pause political donations for the next several months” due to the violent attack on the Capitol on Jan. 6.

Nasdaq’s PAC also said that it has suspended contributions to elected officials who voted to object to the results of the presidential election.

During the certification process, 138 House members and seven senators, all Republicans, voted against Electoral College certification.

“Nasdaq shares the public’s concern regarding the deadly events that took place within the U.S. Capitol building. We hope our policies reflect our optimism about the future of America, the opportunity to heal as a country, to champion inclusive growth and prosperity, and the chance to come together to solve our greatest challenges,” Nasdaq said in a statement.

The CME Group also said that its PAC has suspended all political contributions “for the foreseeable future,” citing the attack on the Capitol.

“In light of this appalling event, the company believes it is critical to reexamine its contribution policies to ensure anyone who receives PAC support shares the values of CME Group,” it said.

The CME said its PAC has historically supported politicians that support free market economics, regardless of political affiliation.
