What is an example of “trust-busting” that Theodore Roosevelt enforced? I keep getting conflicting answers, one saying he supported Northern Security Companies and others saying he broke it up...Can I get help on this, please?

The example of "trust-busting" associated with Theodore Roosevelt is his enforcement of antitrust laws against the Northern Securities Company. In 1902, Roosevelt initiated legal action against the Northern Securities Company, a major railroad holding company formed by a group of prominent financiers, including J.P. Morgan and James J. Hill. The Northern Securities Company was seen as a monopoly that controlled railroads and was perceived to be in violation of antitrust laws.

In 1904, the Supreme Court of the United States ruled in the case of Northern Securities Co. v. United States. The Court, in a landmark decision, ordered the dissolution of the Northern Securities Company, affirming the government's authority to regulate and break up monopolies. This case is often cited as one of Roosevelt's significant trust-busting actions.
