Today's installment of campaign-related news items that won't necessarily generate a post of their own, but may be of interest to political observers:
* Wisconsin Gov. Scott Walker (R) said this morning that if he were elected president, he'd "disown" any international nuclear agreement with Iran on his first day in office. Walker, it's worth noting, does not yet know whether there will be a deal and he has no idea what policies may be included in an agreement.
* New Jersey Gov. Chris Christie (R), who used to support immigration reform, has "quietly signed onto an amicus brief opposing President Obama's executive action on immigration." The legal brief was filed earlier this week.
* Vice President Biden has not yet announced his future plans, but msnbc's Alex Seitz-Wald has an interesting take on where Biden stands and the possibility of a presidential campaign.
* Sen. Ted Cruz (R-Texas) may have succeeded former Sen. Kay Bailey Hutchison (R-Texas), winning her seat in 2010, but Hutchison has no plans to support her fellow Texan. The former senator told msnbc yesterday she intends to support former Gov. Jeb Bush's (R) campaign.
* Sen. Marco Rubio (R-Fla.) claimed this week that President Obama's "entire political machine" went to Israel in the hopes of derailing Prime Minister Benjamin Netanyahu's re-election campaign. As is too often the case, Rubio's claims appear to be at odds with reality.
* Hillary Clinton continues to hire members of her unannounced campaign operation, this week hiring Teddy Goff, the digital director of President Obama's 2012 campaign, as part of her new team of online strategists.
* Indiana's open U.S. Senate race will get its first candidate today, when former state GOP Chairman Eric Holcomb launches his candidacy. Holcomb is a former aide to Sen. Dan Coats (R), who announced his retirement this week.
* And the editorial board of the Wall Street Journal, one of the most Republican-friendly spaces in American media, is apparently unimpressed with Ted Cruz's national ambitions. In an editorial the other day, the paper described Cruz's agenda as "a dream come true for Hillary Clinton."
