President Donald Trump signed an executive memorandum Thursday aimed at investigating ActBlue, the leading Democratic fundraising platform.

The memorandum directs Attorney General Pam Bondi to “investigate allegations regarding the unlawful use of online fundraising platforms to make ‘straw’ or ‘dummy’ contributions or foreign contributions to political candidates and committees, and to take appropriate action to enforce the law."

It specifically names ActBlue as an online fundraising platform being used “to improperly influence American elections.”
