What are congressional members free from while congress is in session?

While Congress is in session, congressional members are generally free from arrest for most civil offenses, allowing them to perform their legislative duties without the distraction of legal issues. This privilege, known as "congressional immunity," does not apply to criminal offenses or cases of treason. Additionally, they cannot be questioned in court regarding their speeches or debates in Congress, ensuring the independence of legislative discussions. This protection is intended to uphold the separation of powers and maintain legislative integrity.
