The House of Representatives in the United States is now controlled by the Democrats. The Senate remains in the control of the Republicans.
The Democrats and Republicans are two political parties in the United States (groups of people with very different ideas about how the country should be run). US President Donald Trump is a Republican.
On Nov. 6, the United States had a big election, called the “mid-term” elections. Americans vote for who they wanted to represent them in two main branches of their government: the House of Representatives and the Senate.
