The US State Department declared it would deny visas to five individuals, among them a ex-European Union official, for allegedly seeking to "force" American social media platforms into suppressing viewpoints they disagree with.
"These individuals and aggressive non-profits have advanced censorship crackdowns by other governments - in each case focusing on US voices and American companies," remarked US diplomat the official.
The former European tech regulator suggested that a "targeted campaign" was underway.
Officials labeled Breton as the "mastermind" of the European Union's online content law, which mandates content moderation on social media firms.
Yet, the act has frustrated some US conservatives who view it as an attempt to silence right-wing opinions. EU authorities denies this.
The official has been in conflict with the billionaire entrepreneur, owner of platform X, over requirements to adhere to European regulations.
EU regulators recently fined X €120m over its blue tick badges – the first fine under the DSA. Regulators stated the platform's system was "deceptive" because the firm was not "meaningfully verifying users".
As a countermove, the platform blocked the Commission from running advertisements on its platform.
Responding to the entry restriction, Breton posted on X: "Addressing the US: Speech suppression isn't where you think it is."
Clare Melford, who heads the British disinformation research group, was included in the sanctions.
US Undersecretary of State Sarah B Rogers accused the GDI of using American public funds "to encourage censorship and targeting of American speech and press".
A representative for the group characterized the entry bans as "a repressive move on free speech and an egregious act of government censorship".
"Their actions today are unethical, unlawful, and contrary to American values," the spokesperson added.
Another figure of the an online hate watchdog, a non-governmental organization that fights digital hatred and false information, was also handed a ban.
The undersecretary labeled Mr Ahmed a "key collaborator with campaigns to weaponize the government against American people".
Also subject to bans were two executives of HateAid, which the US officials said aided in implementing the DSA.
In a statement, the two CEOs called it an "act of repression by a administration that is showing disregard for the legal principles".
"We will not be intimidated by a government that uses accusations of censorship to muzzle those who defend human rights," they added.
The Secretary of State stated that steps had been taken to impose entry bans on "representatives of the international suppression network" who would be "typically prohibited from entering the United States".
"The administration has been explicit that his national sovereignty foreign policy opposes violations of US autonomy. Extraterritorial overreach by overseas regulators targeting US expression is no exception," he affirmed.
