It is about time the government put tougher standards on retirement savings brokers, Vanguard Group founder Jack Bogle told CNBC on Wednesday.

President Barack Obama this week directed the Labor Department to proceed with new rules to rein in conflicts of interest among brokers who advise clients on retirement investments. The regulations would mandate that brokers follow a "fiduciary standard" to prioritize clients' interests over brokers' interests. The brokers would have to disclose any fees or payments they receive for recommending investments.
