Transcript for Democrats launch multiple investigations into Trump

the Ohio river valley. To Washington where another shutdown deadline is looming. Just over a week to go as congressional negotiators work toward an agreement on border security to keep the government open and congressional Democrats defy president trump by launching multiple investigations right now. Mary Bruce is on capitol hill with the latest. Mary, the president is already up early this morning tweeting an attack on one of the investigations.

We've heard from many Republicans, even some of the president's closest allies here on the hill saying that is not a good idea and feel it would set a terrible precedent. 2020, presidential race, Elizabeth Warren continues to be dogged by claims she continued to claim native American heritage and she was forced to apologize.

Reporter: George, the senator there telling us she is sorry that she was not more mindful and sensitive when labeling herself as American Indian but, George, Elizabeth Warren is expected to formally launch her presidential campaign this weekend and she just continues to be plagued by this controversy surrounding her claims of native American heritage.
