This article describes how New York City Mayor Michael Bloomberg plans to donate to Planned Parenthood in a promise to match donations up to $250,000 which is as good as done. This action is in response to the Susan G Komen for the Cure foundation pulling its grants to Planned Parenthood for breast cancer screening, totaling about a $700,000 loss for Planned Parenthood (per year). The Komen foundation pulled their contributions for concern that an impending investigation of Planned Parenthood will hurt Komen's credibility with donors. It would be, apparently, politically unsound for a foundation aimed preventing and finding a cure for breast cancer to fund accessible breast cancer screenings for a company that also allows women easy access to abortions.
The fact that an article is run is an argument in and of itself; the article is arguing that this is an important issue. And although there is not an explicit argument in the article, it can be diagrammed relatively explicitly.
Claim: Bloomberg is donating $250,000 to Planned Parenthood
Evidence: Bloomberg's tweets and statements; quoted saying "politics have no place in health care"
