'Start Here': Partial government shutdown continues, DHS under fire for migrant deaths and American monitored for potential Ebola. What you need to know to start your day.

The partial federal government shutdown is stretching into its second week.

It's Monday, Dec. 31, 2018. Here's what you need to start your day:

1. Government shutdown rolls on as negotiations stall

"Everything is completely stalled and nothing is in the works," a White House official told ABC News Sunday afternoon.

ABC News Chief White House correspondent Jonathan Karl says incoming Acting Chief of Staff Mick Mulvaney is a key player in the talks.

Then, ABC News’ Anne Flaherty tells us the stories of some of the federal workers directly affected by the shutdown.

2. DHS chief defends department after deaths of migrant children

At the heart of the entire shutdown debate is the idea of using American tax dollars to fund a border wall, which the president promised on the campaign trail would be financed by Mexico.

In recent days, the president has since floated the idea of completely shutting down the U.S.-Mexico border and blamed Democrats, without evidence, for the death of two migrant children in US custody in recent weeks.

ABC News contributor and former Department of Homeland Security Acting Undersecretary in the Obama administration John Cohen says border officials seem to have been caught off guard by the influx of migrants, despite warnings from the president himself that many were on the way.

3. American to be held after potential Ebola exposure in Congo

In Nebraska, an American who was giving medical assistance in the Democratic Republic of Congo has been placed in a secure area of a hospital due to their potential exposure to the Ebola virus.

While a spokesperson at University of Nebraska Medical Center said the person has yet to display any symptoms, their identity is being kept secret as some nervously weigh the risks of the disease spreading in the U.S.
