The emancipation proclamation was probably the most controversial thing he did. Replacing the popular General McClellan invited criticism, especially since his replacement, Gen Burnside did not do much better.

His apparent approval of strong measures taken against civilian anti-war agitators no doubt provoked some controversy.
