NBC News today named Chris Jansing as Senior White House Correspondent. Peter Alexander was named National Correspondent. Jansing will report primarily for NBC Nightly News, providing day-to-day coverage of the Obama administration and White House politics. Alexander will report not only on the White House but also on national affairs beyond Washington DC. Jansing will return to NBC News full time next month, relocating from New York to join Todd, Alexander, and Kristen Welker in the unit. MSNBC said it will announce Jansing’s replacement in the coming weeks.
