What's one thing washington put into place that's still relevant to the presidency today? how did he use this policy? how does biden use this policy! (please answer all parts ^^;)

Washington is responsible for establishing the Inaugural address he also established the Cabinet System. Most Presidents use their Inaugural address to present their vision of America and to set forth their goals for the nation. Some of the most eloquent and powerful speeches are still quoted today. In forming a cabinet, Washington rejected the two existing management models used by the British. He would be more than a ceremonial head of state like a monarch but less of a micromanager than a prime minister. Instead, he would delegate authority to his department heads and closely supervise their actions. Biden used this Inaugural Address on January 20th to give his big speech about America.
