President Andrew Johnson said that "this is a country for white men." How did he act on this belief?

he vetoed most reconstruction legislation.

Explanation:

After the Civil War, Radical Republicans in Congress and President Andrew Johnson differ over the terms and conditions for readmitting the withdrew states to the Union. President Johnson saw Reconstruction as an official duty and blocked congressional activities.

Congress tried to check the power of the presidency, which had extended in wartime, and took a less appeasing position toward the previous Confederate states on issues of loyalty, governance, and the privileges of black citizens. In 1867 and 1868 Congress passed four Reconstruction Acts over Johnson's vetoes.
