(Bloomberg) -- Beto O’Rourke proposed limiting presidential pardon power and strengthening a constitutional prohibition against elected officials using the powers of their offices to enrich themselves.

O’Rourke, a former Texas congressman whose presidential campaign has struggled to gain traction among Democrats, said on Tuesday he would seek to make it a federal crime to attempt to secure or accept “assistance from a foreign power for personal profit or political gain” and that he’d also bar non-financial assistance from a foreign state in an election.

He also proposed a constitutional amendment banning presidents from issuing pardons to people connected to investigations in which the president or a family member is a target, subject or witness.

O’Rourke renewed his call for lawmakers to remove President Donald Trump from office and said the other measures he rolled out Tuesday would help ensure “that Trump -- and every president who follows -- will never be above the law, or able to welcome foreign interference in our democracy.”
