Legislative branch- the House has the ability to bring forth bills of impeachment. They also can bring forth introduce bills of appropriation...aka introduce tax bills and bills that deal with revenue.
Senate- they are the ones who confirm presidential appointments of any sort(aka I believe Eric Holder had to be approved by the Senate before becoming head of the Justice Department), ambassadors also must be approved by the senate. The Senate can strike down the bills of revenue or any bills that the House introduces. One other thing, the Senate members are the only ones who are allowed to hear impeachment cases and decide the verdict of the one being tried.
Hopefully this helped and good luck.
The president of the United States
The answer is, "She explains the weather forecast to reassure her."
The League of Nations, frankly, sucked.
Other factors included:
The US didn't join.
The Treaty of Versailles (joining the League was like a punishment)
Limited Variety of Nation in the League (many countries weren't invited to join)
And, the League was practically unable to negotiate disputes.
