Despite his recent campaign woes, Donald Trump remains only a few percentage points behind Hillary Clinton in national polls, according to RealClearPolitics’ poll average.

One recent USC/L.A. Times poll showed a virtual tie between the two candidates. As always, polls should be taken with a grain of salt, but the numbers suggest that maybe Trump’s support hasn’t taken much of a hit despite turbulence within his campaign. Mr. Trump, who recently challenged Clinton to release more detailed medical records, is expected to give a speech this week in Arizona on immigration amid questions about his changing stance on undocumented immigrants.

On our weekly political roundtable, AirTalk’s experts dive into all of this and more as we preview the week on the campaign trail and talk about the storylines you need to know this week.
