I'm sitting in the White House press briefing room awaiting a presidential press conference, which has been moved from the Rose Garden to this room. (Why? Too much humidity for the president?) And I'm thinking of a question, just in case.....Will you fight for a public health option by mobilizing your millions of supporters? Will you oppose a cap-and-trade bill that contains a big giveaway to polluters? Are you satisfied with the intelligence you've received on Iran? Have you consulted with any outside-the-government experts on Iran? If so, who? Are you going to be more transparent than the Bush administration and release the White House visitors logs? Forget about smoking, have you been drinking?

It's been a busy day or two for me. I've been blogging and Twittering much about Iran, and a Twitterer in Iran informs me that this blog and the Mother Jones website have been blocked in Iran by the autocrats of Tehran. It's an honor.

And last night, I trekked through woods, brambles, and poison ivy to reach the site of the tragic DC metro crash, which was just a mile or so from my house. I'm obsessive about finding alternative routes to avoid traffic. Thus, I was familiar with side streets that allowed one to get close to the site. Then I had to bushwhack my way to the tracks. I followed a culvert next to the railroad fence for about a quarter of a mile and found a small opening. I crawled through and walked along the gravel, right up to the crash. I snapped several iPhone photos before a cop approached and ordered me to leave. "It's a crime scene," he shouted, and he threatened to confiscate my phone. I quickly scurried up a steep hill next to the New Hampshire Avenue bridge--took a few more photos--and emerged in a cordoned-off area. I was surrounded by police officers and rescue workers. I didn't say anything, kept my head down, and quickly walked off. Here are the pics., several of which were featured on Good Morning America this AM. (A producer found them on Twitter and asked me for permission to use them.) And for a good sum-up of questions raised by the crash, check out JIm Ridgeway's take here.

Now back to pondering queries worthy of a president, just in case.
