The House votes to approve or reject the bill. Than the bill goes back to the committee and they approve or make changes. It will g back and forth until the bill gets to the president. If the president accepts the bill, it becomes a law. If the president "vetoes" the bill, it goes all the way back to the starting line. All the houses are equal, and a bill may take years and still not become a law. It can take the rest of someone's life, it all just depends what the different houses think about the changes and acceptions or the bill.
yes if the officers have probably cause and have at least consent or a search warrant than the officers have every right to search the home if the other is in absent of their own home.
