Congress does not directly decide the officials in the executive branch of government. The officials in the executive branch, such as the President and various department heads, are typically appointed by the President and confirmed by the Senate. However, Congress does have the power to oversee and investigate the actions of these officials, and can also impeach and remove them from office if necessary.
