No. The president pro tempore of the Senate, the longest- serving member of the Senate, is third in the line of succession but the Senate majority leader is not on the list.
Congress, as a whole does not vote on presidential appointments. It is only the Senate that must give its advice and consent to presidential appointments.
The senate pro tempore is third in the line of presidential succession, behind the vice-president and the Speaker of the House. ( I hope this is what you want to know.)
The Senate
After the Speaker of the House, the next in the presidential succession order is the President pro tempore of the Senate. Following the President pro tempore, the line of succession continues with the members of the President's Cabinet, starting with the Secretary of State. This order is established by the Presidential Succession Act of 1947.
The order of succession for the presidency according to the Presidential Succession Act of 1947 is as follows: Vice President, Speaker of the House of Representatives, President pro tempore of the Senate, and then the Cabinet members in the order of their department's establishment.
-Congress, House of Representatives, Senate
The Electors
Congress votes on and confirms or denies Presidential nominees and or treaties Congress being the Legislative branch of American Government comprised of the House of Representatives and the Senate.
They are vice president, speaker of house and president pro tempore of senate.
The fourth position in the presidential line of succession is the Secretary of State. If both the President and Vice President are unable to serve, the Speaker of the House of Representatives follows, followed by the President pro tempore of the Senate, and then the Secretary of State. This order is established by the Presidential Succession Act of 1947.
Most presidential appointments, including federal judges, cabinet members and ambassadors, require a simple majority vote of the Senate. Mid-term appointments of vice presidents require a simple majority vote of both Houses of Congress, and treaties require a two-thirds majority vote of the Senate.
