TVNewser has learned and NBC News confirms that Los Angeles-based correspondent Jennifer London is leaving the network. Her contract was not renewed. Longtime MSNBC anchor Chris Jansing will be filling-in in the Los Angeles bureau for the next four to six weeks. Most recently Jansing has been anchoring the 3-5pmET hours on MSNBC.

(Full disclosure: Chris Jansing and I worked together at MSNBC. And for inquiring minds: no, the tip did not come from her.)
