Who has power to impeach a governor of Illinois?

Answer 1

The Illinois House of Representatives. From the Illinois constitution SECTION 14. IMPEACHMENT

The House of Representatives has the sole power to

conduct legislative investigations to determine the existence

of cause for impeachment and, by the vote of a majority of

the members elected, to impeach Executive and Judicial

officers. Impeachments shall be tried by the Senate. When

sitting for that purpose, Senators shall be upon oath, or

affirmation, to do justice according to law. If the Governor

is tried, the Chief Justice of the Supreme Court shall

preside. No person shall be convicted without the concurrence

of two-thirds of the Senators elected. Judgment shall not

extend beyond removal from office and disqualification to

hold any public office of this State. An impeached officer,

whether convicted or acquitted, shall be liable to

prosecution, trial, judgment and punishment according to law.
