The influence of Congress on the presidency has varied from period to period depending on factors such as congressional leadership, presidential political influence, historical circumstances such as war, and individual initiative by members of Congress. The impeachment of Andrew Johnson made the presidency less powerful than Congress for a considerable period afterwards. The 20th and 21st centuries have seen the rise of presidential power under politicians such as Theodore Roosevelt, Woodrow Wilson, Franklin D. Roosevelt, Richard Nixon, Ronald Reagan, and George W. Bush. However, in recent years, Congress has restricted presidential power with laws such as the Congressional Budget and Impoundment Control Act of 1974 and the War Powers Resolution. Nevertheless, the Presidency remains considerably more powerful today than during the 19th century. Executive branch officials are often loath to reveal sensitive information to members of Congress because of concern that information could not be kept secret; in return, knowing they may be in the dark about executive branch activity, congressional officials are more likely to distrust their counterparts in executive agencies. Many government actions require fast coordinated effort by many agencies, and this is a task that Congress is ill-suited for. Congress is slow, open, divided, and not well matched to handle more rapid executive action or do a good job of overseeing such activity, according to one analysis.
