she's certainly feeling the pressure there. in fact, she's heading back to nevada again this week. you can hear in her voice today her campaign is telling me they are bracing for an extremely they say it all comes down to turnout. we'll see on saturday. >> all right, cecilia vega with us tonight. thanks, as always. now to the battle over the supreme court tonight. just a short time ago, president obama doubling down on his promise to nominate a candidate to replace justice scalia. and this image tonight, justice scalia's chair, his bench, his courtroom door all draped in black. and democrats pointing to this image tonight. president reagan in 1987, just 13 months to go in his second term. kennedy, of course, later confirmed. but republicans tonight are rejecting that argument. abc's chief white house correspondent jonathan karl on the president's message to the senate, just moments ago. >> reporter: it will be in the where antonin scalia's body will lie in repose friday, a public viewing not far from that chair, now cloaked in black, he used for his 30 years as a justice. today in california, president obama paid tribute to scalia, as a supreme court giant. but also made it clear, he's ready to fight to replace him. >> i intend to nominate somebody to present them to the american people, to present them to the senate. i expect them to hold hearings. i expect there to be a vote. >> reporter: but republicans remain dug in, insisting the next president should name scalia's replacement. the president today pointed out there is precedent for the senate confirming a justice during a president's final year in office. president reagan's nominee, anthony kennedy, was confirmed in february 1988. but kennedy's case is an unusual one. the vacancy came the previous year, in july 1987, when justice lewis powell resigned. reagan first nominated robert bork, who the senate rejected controversial kennedy in november 1987. the senate confirmed him three months later, 97-0. democrats say with 11 months left in obama's presidency, there's plenty of time to confirm a justice. >> and jon karl with us from the white house tonight. and jon, a reporter asking the president, should we assume you will nominate a moderate? how did the president answer? >> reporter: well, he said we should make no assumptions. but the bottom line here, david, is that the president has a choice. he can nominate a liberal who would energize democrats during had election year, or dominate a moderate who has had bipartisan support. i expect he will go in that direction, making it harder for republicans to reject that person, because it's somebody who republicans have supported in the past. >> making it clear that nomination is coming. jon karl live at the white house. jon, thanks to you. now, to that major health headline we reported on last night here. antacids to dementia later on. products like prilosec, nexium, prevacid. researchers say they are linked to a possible 44% increase in the risk of dementia. abc's chief medical editor dr. richard besser tonight answering your questions, and if you are concerned, what you can do about heartburn instead. >> reporter: tonight, reaction to a study that hits people where they hurt -- heartburn -- and forecasts what they fear -- the possibility of dementia. >> basically, my entire family takes prilosec daily. and it's very disturbing. >> reporter: but the study only looked at those over age 75 who took prescription heartburn drugs like prilosec or prevacid on a regular basis. and while it found an increased risk of dementia, it doesn't prove that the drugs were the cause. >> can't afford to let heartburn get in the way? >> reporter: americans spend more than $10 billion a year on these two main classes of heartburn medicines. protein pump inhibitors and h-2 blockers. available by prescription or over the counter. but look at this -- it's on the label. you're only supposed to use the over the counter ones for two weeks. the prescription ones, for most people, just for a few months. because i want to get back to that point he just made. a lot of people take these drugs for heartburn, but the directions, as you point out, are really important here. >> reporter: yeah, that's right. i mean, the label is really clear. you shouldn't take these drugs for more than 14 days. if you still have heartburn at that point, see what else your doctor can suggest. >> and for folks at home who might be concerned about these drugs after this study, is there anything else we can do about heartburn? >> reporter: well, there are a few things. if you're overweight, losing weight will help. raise the head of your bed when you go to sleep. and look for any triggers for your heartburn. for many people, it's acidic things like coffee and spicy food. >> raise your head when you go to bed?

who kept her from coming home? >> reporter: what finally led police to franklin's suburban door was dna, but not his own. his dna was not in databases, but his son's was. so, investigators trailed franklin until they got a sample. >> slice of pizza, i think a fork, there was a napkin. >> reporter: when they raided his home in 2010, they found pictures of hundreds of other cold case investigators say that among the women he photographed were several others he's suspected of killing. now, they've identified some of those women, but disturbingly, not all of them. if convicted, he faces the death penalty. david?
