It's Wednesday, Jan. 9, 2019. Thanks for choosing to start here.

1. Trump talks border security in Oval Office address

Last night, President Donald Trump delivered a prime-time address on border security from the Oval Office.

ABC News fact-checked his claims, which we break down with our powerhouse political team in addition to discussing how Democrats responded.

2. Trump to meet with Democrats again on shutdown

The president is expected to meet with congressional leaders at the White House as the government shutdown, the second longest ever, enters its 19th day.

But last night, neither side seemed to offer a compromise to reopen the government. ABC News Senior Congressional Correspondent Mary Bruce tells us pressure is building on lawmakers to act.

"You now have all of these federal workers, hundreds of thousands of them, on the verge of missing their first paycheck," Bruce says. "Lawmakers here are going to start to feel that as constituents start voicing their frustration."

3. Lawyers inadvertently reveal Mueller accused Manafort of sharing poll data with alleged ex-Russian agent

Special counsel Robert Mueller is accusing former Trump campaign chairman Paul Manafort of lying about sharing polling data with a Russian man allegedly connected to Russian intelligence, according to an unredacted filing by Manafort's attorneys.

The court documents were Manafort's response to charges that he violated his plea deal, but his defense counsel failed to adequately redact sections of the filing.

If the accusation of handing over polling data is found to be true, ABC News Chief Justice Correspondent Pierre Thomas tells us, it could be evidence of a senior Trump campaign official colluding with Russians during the 2016 presidential race.
