Answer:
He feared the control Standard Oil had in the market.
Explanation:
Theodore Roosevelt, who became president in 1901 after the assassination of William McKinley, embodied the progressive movement. For him, the balancing force against corporate power could only be one: the government.
Standard Oil has become Roosevelt's favorite target. However, he sought big business support for his 1904 campaign. A writing president, especially as prolific as Roosevelt, would surely be sensitive to praise. But this "seductive approach" from the company's chief executive didn't work
Roosevelt feared Standard Oil's control of the market, so in November 1906 the Roosevelt administration filed a lawsuit against Standard Oil, accused, under the 1890 Antitrust Sherman Act, of conspiracy to dominate the oil. trade. As the process proceeded, Roosevelt fanned the flames of public outrage. The War Department announced that it would not buy corporation products.
