The correct answer to this open question is the following.
The two agencies will be the U.S. Secret Service and the U.S. Customs and Border Protection.
After the terrible terrorist attacks of September 11, 2001, President George W. Bush ordered the creation of the Department of Homeland Security to increase the protection of the United States under the permanent threat of terrorist groups.
Some agencies that belonged to other departments were moved under this new agency. That was the case of the U.S. Secret Service and the U.S. Customs and Border Protection.
Due to its importance and reach, these two agencies are always in the news and are part of the US public opinion. The advantages of publicizing the work of these agencies are that American citizens are informed about the function and importance of what they do. The disadvantages of publicizing the work of these agencies are that they manage exclusive and secret information due to security reasons and when information ends up in the news, it could compromise officials, programs, and the security of the country.
The U.S. Secret Service has to protect top US Officials, including the President. Its job is top-secret for obvious reasons. But many times, newspapers or reporters find ways to filter some news that ends up on the morning news and then it's public. The same thing with U.S. Customs and Border Protection. This agency handles critical information about who enters or leaves the country. It is delicate and critical information that when it makes the news, compromises the security or operation of a program.
