"Obstruction of Congress" refers to actions that interfere with the legislative process of the United States Congress. This can include refusing to provide requested documents, failing to comply with subpoenas, or preventing witnesses from testifying. Such actions can hinder Congress's ability to conduct investigations or carry out its duties effectively. This concept is often discussed in the context of impeachment proceedings or investigations into the actions of government officials. When individuals or entities obstruct Congress, it can lead to legal consequences and may be viewed as undermining the democratic process.
