"All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives."--Article I, Section 1,
The Constitution of the United States
The Constitution grants specific powers to Congress. These include the
ability to borrow money, provide for a monetary system, regulate
commerce, establish lower federal courts, maintain a military, and
declare war. Congress also handles all revenue bills and has the ability
to tax.
Taxing allows Congress to raise necessary monies to finance the government so that it can provide important services. Taxes raised by the federal government fund interstate highways, federal law enforcement, and our military, among other things.
One of Congress' most important jobs is debating and passing the laws
that govern our country. In order to create a new law, a member of the
House or Senate introduces a bill. The bill is then referred to one or
more committees that discuss the bill and make any desired changes. Once
in final form, the bill is debated on the floor of the chamber where it
was first introduced, and amendments may be offered, accepted, or
rejected at that time. If the legislation is passed by a final vote, it
is referred to the other chamber. There, the bill goes through similar
committee meetings and debates and undergoes another vote. Once both
houses of Congress approve the same version of a bill, it can finally be
sent to the President for his approval or veto.
