Answer:
In 2007, Democratic congresswoman Nancy Pelosi became Speaker, the highest position in the House of Representatives and second after the vice president in the line of succession.
Step-by-step explanation:
The speaker is the political and parliamentary leader of the House, and is simultaneously the body's presiding officer, the de facto leader of the body's majority party, and the institution's administrative head. So when Nancy Pelosi became the Speaker, she had the highest position in the House of Representatives.
