During his presidency, many members of Congress felt that Theodore Roosevelt overstepped the executive powers afforded to him as President of the United States. Roosevelt felt that large industry required an involved government, and used this rationale to exert influence over negotiations between labor unions and companies.
Another instance where Roosevelt exhibited questionable use of power was during the building of the Panama Canal. He did not obtain Senate or House approval to create the canal, and used his influence to recognize the Republic of Panama as a new nation so that the project could be completed faster. His actions towards Columbia, the original nation where the canal was located, resulted in strained diplomatic relations with other Latin America countries.
